ME7660中文资料DC/DC switching regulators数据手册UTC规格书

描述 Description

ME7660 is a charge pump DC-DC voltage converter usingAL-gate CMOS technology and optimization design. It converters a+1.5V to +10V input to a corresponding -1.5V to -10V output using onlytwo external capacitors, eliminating inductors and their associatedcost, size and EMI. The on-board oscillator operates at a nominalfrequency of 10KHZ. Operation below 10 KHZ (for lower supply currentapplications) is possible by connecting an external capacitor from OSC to ground.

特性 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
