General Description

SOP-8

The KM7660 is a pin-compatible replacement for the Industry

standard ICL7660 charge pump voltage converter. It converts a +1.5 V

to +10 V input to a corresponding -1.5 V to -10 V output using only

two low-cost capacitors, eliminating inductors and their associated

cost, size and EMI.

0.15

1.50

The on-board oscillator operates at a nominal frequency of 10 kHz.

Operation below 10 kHz (for lower supply current applications) is

possible by connecting an external capacitor from OSC to ground

(with pin 1 open).

The KM7660 is available in an 8-pin SOIC package in extended

temperature range.

Features

● Converts +5.0 V Supply to -5.0 V Supply
