LMC7660

Switched Capacitor Voltage Converter

General Description

The LMC7660 is a CMOS voltage converter capable of con-

verting a positive voltage in the range of +1.5V to +10V to

the corresponding negative voltage of −1.5V to −10V. The

Features

n Operation over full temperature and voltage range

without an external diode

n Low supply current, 200 µA max

n Pin-for-pin replacement for the 7660

n Wide operating range 1.5V to 10V

n 97% Voltage Conversion Efficiency

n 95% Power Conversion Efficiency

n Easy to use, only 2 external components

n Extended temperature range

LMC7660 is

pin-for-pin replacement for the

industry-standard 7660. The converter features: operation

over full temperature and voltage range without need for an

external diode, low quiescent current, and high power effi-

ciency.

The LMC7660 uses its built-in oscillator to switch 4 power

MOS switches and charge two inexpensive electrolytic ca-

pacitors.
