SEARCH TIPS & EQUIVALENT ELECTRONIC PARTS: Please use top-right search box or your Browser Search / Find feature to locate the specific Items of interest or just browse webpage. Because of huge variations in Power IC part #s, Power ICs are also listed by their base part #s, so your first search for a part should be by its base part # (e.g. 7915 for LM79L15ACM) - if we sell any variation of the part #, you'll find it, then scroll down from there (the base or core part # is the number which remains after removing all prefix and suffix letters and sometimes middle letters). We listed many electronic parts by more than one name and name variation (e.g. "LM2575T-12", "LM2575", "LM 2575T" and "LM 2575", etc.). There are many equivalent power ICs, and many ICs which have the same pinouts but while not exactly equivalent can in some circuit designs substitute and even improve over the other - if you can't find your exact electronic parts, search for the power semiconductor part's function and functional variations (e.g. "adjustable voltage regulator", "transil diodes," etc.). Top-right search box finds parts even if you only have small snippet of the power semiconductor name or part # - even if in middle of name/part #. If you still can't find your power electronics parts, try by other name and part # variations. If you still can't find power semiconductor parts then search our other likely webpages, see SITEMAP for links. Your efforts might save you money as some electronic parts / electrical parts are now either unavailable or rare and costly - if you can find more common electronic part equivalents and/or buy in quantity, savings of 90+% per part are possible, and you can breathe new life into older designs and equipment. Especially for integrated circuits (ICs), the main specs to look for is based on the base part #, look for these specifications from the electronic part's datasheet, and then find electronic parts with matching critical datasheet specs (usually not all specs are critical). Also look for Milspec, ECG, NTE and other electronic parts equivalents, and vice-versa.

ITEM SPECIFICATIONS - DATASHEETS & CIRCUIT DESIGNS: For datasheets for integrated circuits, transistors, rectifiers, diodes, and most other electronic parts, we recommend the following great electronic parts database websites: Alldatasheet.com, Datasheet Archive, and DatasheetCatalog.com. Electronic design tutorials, electronic applications, specific circuit designs and even patent data can be found using Google, Yahoo, MSN, etc., as well as many books filled with electronic parts datasheets and circuit designs. While we have tried to be 100% accurate in our descriptions, please freely let us know any errors or omissions made herein, preferably by providing us a pdf URL for the specific Item either from the manufacturer or from an Online datasheet database, such as, Alldatasheet.com, Datasheet Archive, Datasheet Catalog.com.

(2) WIDE VOLTAGE RANGE
VOLTAGE DOUBLER BOOST VOLTAGE REGULATORS /
2X STEP-UP VOLTAGE REGULATORS / BOOST DC/DC CONVERTERS /
STEP-UP DC/DC CONVERTERS (OUTPUT VOLTAGES 2.7 VDC TO 40 VDC) /
LOW FREQUENCY AMPLIFIER ICS

New old stock (NOS), DIP/DIL ICs. These highly versatile and compact boost voltage regulator / step-up voltage regulator / boost DC/DC converter / step-up DC/DC converter ICs are very useful. These wide-voltage-range voltage-doubler DC-to-DC converters double the 1.5V - 20.0V input DC voltages to 2.68V - 40.0V output DC voltages (output VDC is slightly less than double input voltages for less than 10VDC input). From our measurements (tested with a 1K ohm output load resistor): 1.5VDC input => 2.68VDC (3 VDC nominal) output, 3.0VDC => 5.62VDC (6 VDC nominal), 5.0VDC => 9.56VDC (10 VDC nominal), 6.0VDC => 11.62VDC (12 VDC nominal), 9.0VDC => 17.8VDC (18 VDC nominal), 10VDC => 20VDC, 12VDC => 24VDC, 15VDC => 30VDC, 18VDC => 36VDC, 20VDC => 40VDC. Note that 20VDC input voltage was highest voltage we use them for continuous use, both higher input and output voltages were achieved in short-term tests and may also be OK for continuous use. Output continuous power rating tested by us was 2 watts (enough to power several ICs). 1.5VDC => 2.7VDC means that with one AAA, AA, C, D, Nicad, Lithium-ion cell battery you can power low voltage ICs (e.g. LM358, NE532, WP901) without using an expensive and limited LM3909. 5.0VDC => 9.6 VDC means you can use a 5VDC power supply (e.g. TTL power supply) to also power 40xxx CMOS and other higher voltage ICs and transistors. Furthermore, by using two of these boost voltage regulators, you can produce 4X +V or -V output voltages or 2X ±V output voltages to within 1% of each other (inputs wired in parallel, outputs wired in series). These versatile and compact boost DC voltage regulators/converters replace our previous need to maintain a stock of dozen typical DC boost voltage regulators/converters with each type strictly limited to specific voltages.

These voltage-doubler boost DC/DC converters are about the same length and width of a 24-pin DIP IC and about 1/2" thick. They are each made with 23 pins total (0.1" apart; 1 pin omitted by its maker), of which only 4 pin pairs are used - 1 pair on one end and 3 pair on other end (the rest of the pins test open-circuit and have no known function, we usually clip them off). Each opposite sets of pins are identical (e.g. pins 1 and 24 are same, pins 10 and 15 are same, pins 11 and 14 are same, pins 12 and 13 are same), so if you wish you can actually install this IC on either of its sides as a SIP. Since the input and output pins are at the ends of the IC, you can mount other parts, preferably on backside of your circuit board (e.g. a DIP IC of 16 total pins fits perfectly) easily inside the footprint of the DC-to-DC boost converter IC). The DIP pins on these boost converter ICs extend 3/16" below the body and there is recessed area the general size and shape of a 16-pin DIP IC on the underside center; you can also conceal another thin IC(s) and/or other thin electronic parts underneath the DC boost converter IC's body (consider heat dissipation issues when doing this) to hide some of your circuitry from reverse engineering.

AMPLIFIER APPLICATIONS: Since the DC/DC boost converter IC's input and output pins are electrically isolated from each other, you can also use these step-up DC converters for isolation applications and to eliminate noisy ground loops and 50 Hz / 60 Hz and RFI interferences. No doubt they contain a built-in transformer to provide this isolation, which means that the device must chop-up the DC voltage to a frequency which the transformer will work at. We have found that these ICs are not limited to DC inputs, but will also boost low-frequency AC inputs upto 10 Hz like a constant gain opamp (with no feedback). Consequently, we find these boost converter ICs very useful as low-pass filters and low-frequency DC-coupled, gain=2 amplifiers (i.e. "G=2 opamps") - especially useful for some transducers and sensors and infrasonic applications. Because these ICs are essentially chopper amplifiers, you won't likely need a fresnel lens or rotating fan for thermal sensor applications. Since its upper frequency is about 10 Hz, it is very immune to 50Hz / 60Hz interference as well as RFI. So if you also need isolated, DC-coupled, chopper amplifier-type, gain=2 amplifiers, these ICs may be ideal for you.

We do not know what the actual specs are for these unmarked and unknown ICs, so we identify them with our own proprietary markings in our designs (protects our designs from reverse engineering). And because we cannot identify their actual part #, we cannot guarantee their specs - we can say that we have used them for various applications described herein and they have always worked fine. If these boost DC converters / boost regulators / low-frequency amplifiers are what you need, buy this Item, test them at your end, and should you like them, let us know and we will list herein any quantity up to 400 ICs at both reduced per IC cost and per IC S/H cost (cost reductions depend on quantity ordered) for you to buy what you need. We include pin-outs when shipped. These boost DC converters/regulators / step-up DC converters/regulators ICs are shipped in antistatic tube or foam.

(12) LM7812 VOLTAGE REGULATOR on HEATSINKS
+12 VDC, LM 7812 +12VDC VOLTAGE REGULATORS

New old stock (NOS) SOIC TO-220. These LM7812 positive 12VDC voltage regulator ICs on heatsinks are circuit clips (used voltage regulator ICs). We have sampled-tested them under 12-ohm loads and every single one tested 100% perfect (10% randomly selected sample). The LM7812 ICs are riveted to their T0-220 heatsinks for a snug thermal connection, and were mounted with conductive paste. IC leads extend 1/4" beneath heatsink for insertion into PC boards, solderless breadboards and prototype boards (for easier board insertion, you can use wire cutters to cut ends of leads at a slant to point them). One wing of the heatsinks is bent from the normal 90 degree position to about 45 degrees so that clipping tool could get a clean, even flush cut, but is easily and quickly bent back without breaking using pliars. TO-220 heat sinks like these are expensive (much more expensive than the LM7812), and the cost of mounting voltage regulators on heatsinks in time, effort and money is substantial, especially in quantity, so don't let this great deal get by you. Of course, if you need these expensive TO-220 heat sinks for some other TO-220 voltage regulators (e.g. LM7805, LM7815, LM7908, LM317, etc.), TO-220 power opamps (e.g. TIP120, TIP32, etc.), or other part, you can always easily drill, punch or grind off the rivets to replace the LM7812s.

(25) INTERSIL ICL7660CPA / ICL 7660CPA
NEGATIVE VOLTAGE CONVERTER ICS (-5VDC OUTPUT)

New old stock (NOS) ICL7660 negative voltage converter (-5 VDC output) DIP/DIL ICs. ICL 7660 type Intersil ICs, equiv. to 7660 ICs and to the Maxim Max1044 (Max 1044). The ICL7660 is by far the easiest, fastest, most versatile, most compact and cheapest way to add a negative power supply voltage to a circuit that has only a positive power supply voltage! Can also be wired with a few parts to be a positive voltage doubler or positive voltage tripler! Absolutely invaluable for the designer! You can connect these up to even double the current if you wish! When used in conjunction with a single cell battery (1.5 VDC AA, AAA, C, D, coin battery/cell), because the negative voltage output almost doubles the total VDC to close to 3 VDC, you can use it to operate low-voltage ICs like the LM358 and NE532 from a single 1-cell battery! Permits external clocking and shutdown. Requires only 2-3 common capacitors and 2-3 diodes to operate (combination of which depends upon desired output). Especially ideal for bipolar opamps, cheapo dynamic RAM (as compared to static RAM), microprocessors and microcontrollers that require negative power supplies (e.g. 8080 series), data acquisition systems (ADC, DAC, etc), single-cell power supply circuits, and some transducers. If you are serious about electronics, you absolutely must keep in stock a good supply of these ICs. We also sell Maxim ICL7665A voltage monitors. Shipped in antistatic tube.
