ICL7660CPA by Intersil
Voltage Doubler / Tripler / Splitter or Polarity Inverter
A basic circuit needs only (2) capacitors! (NOT included)
Up to 99.9% Conversion Efficiency!
Price is for a quantity of
(4)
pieces.
PLUS: Check out the datasheet and application links and FREE Bonus below.
The ICL7660 is an incredibly efficient, inexpensive and extremely easy way to generate a
NEGATIVE
supply voltage from a
POSITIVE
supply!
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, R
L
=
∞
98% Power Efficiency, R
L
= 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 10 VDC supply
Great for battery powered circuits
Ideal for Comparators, RAM & Op-Amps
requiring split supplies up to ± 10 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 datasheet shows you how.

BONUS Schottky Rectifiers
For a limited time, we are including (10) 1N5817 Schottky Rectifiers for
FREE!
with every purchased lot. That's a value and perfect for making voltage doublers and triplers.
Want to know why?
The 1N5817 Schottky diode has a very forward low voltage drop (V
D
) 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 gain, especially when using low input voltages.
Don't wait! The Bonus offer may be withdrawn without notice.
