ME7660G-SO8-R

Manufacturer Part Number
ME7660G-SO8-R
Description
CHARGE PUMP DC-DC VOLTAGE CONVERTER
Manufacturer
UTC [Unisonic Technologies]
Datasheet
ME7660
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.
* 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
