CHARGE PUMP DC-DC

VOLTAGE CONVERTER

DESCRIPTION

ME7660

is a charge pump DC-DC voltage converter using

AL-gate CMOS technology and optimization design. It converters a

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

two external capacitors, eliminating inductors and their associated

cost, size and EMI. The on-board oscillator operates at a nominal

frequency of 10KHZ. Operation below 10 KHZ (for lower supply current

applications) is possible by connecting an external capacitor from OSC

to ground.

FEATURES

* Converts +5V Logic supply to +5V

* Wide input voltage range:1.5V~10V

* Efficient voltage conversion:99.9%

* Good power efficiency:98%

* Low power supply:50uA@5Vin

* Only two external capacitors required

* Compatible with RS232 negative power supply standard

* No Dx diode needed for high voltage operation
