(6) - ICL7660CPA by Intersil
Negative Voltage Converter / Doubler / Tripler / Splitter
The basic circuit needs only (2) common capacitors!
Up to 99.9% Conversion Efficiency!

Auction is for a quantity of (6) pieces.

Check out the Buy-it-Now! Bonus below.


The ICL7660 is uniquely effective as an inexpensive and extremely easy way to generate a negative supply voltage from a power supply that has a single positive output voltage!

FEATURES:

  • Greatly simplifies power supply design
  • Basic operation requires only (2) capacitors
  • DIP8 package - easy wiring
  •     -V Negative output from a positive source
  •     2xV Voltage doubler
  •     3xV Voltage tripler
  •     ½V Voltage splitter
  • 20 mA load possible
  • 99.9% Voltage Conversion Efficiency, RL = ∞
  • 98% Power Efficiency, RL = 5K Ohms
  • Parallel for higher currents (any # of units)
  • Cascade for higher voltages (up to 10 units)
  • Very Low Power Consumption at Idle
  • Uses a single 1½ to 12 VDC supply
    Great for battery powered circuits
  • Ideal for Comparators, RAM & Op-Amps
    requiring split supplies up to ± 12 VDC
    at up to 20 mA
  • Efficient voltage multiplier for Varactors
This is an amazingly versatile but
very simple-to-use device.

The popular LM3909 can't flash those High Intensity LEDs with a single 1.5V battery. This IC can boost a AAA battery to about 2.75 Volts to the LM3909 under load to lite up those high intensity LED's requiring higher voltages. Parallel wire ICL7660's to provide needed current. The datasheets show you how.

Intersil ICL7660 (255K PDF)
Maxim 7660 (117K PDF)

Maxim AN010 (59K PDF)



Buy It Now - BONUS Schottky Rectifiers

If you are the 1st bidder and if you choose eBay's  option for this item, you will also receive (10) 1N5817 Schottky Rectifiers for FREE! That's a $2+ value and enough for (5) easy-to-build voltage doublers.

Want to know why?

The 1N5817 Schottky diode has a very low voltage drop (VD) of about 0.2 volts @ 20 mA compared to 0.7 volts for the typical silicon rectifier (e.g. 1N4001). The improved efficiency of the voltage doubler circuit, will boost the output voltage by 1.0 volt! That's a very significant increase, especially when using low input voltages.

Don't wait! The BIN bonus is only available to the 1st bidder.
To receive this offer, you must Buy It NOW!
