CHARGE PUMP DC-DC VOLTAGE CONVERTER

 

 

DESCRIPTION

 

UTC UTL7660H 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 20KHZ. Operation below 20KHZ (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: 55μA @ 5 Vin

Only two external capacitors required

Compatible with RS232 negative power supply standard

No Dx diode needed for high voltage operation
