UNISONIC TECHNOLOGIES CO., LTD UTL7660 Preliminary CHARGE PUMP DC-DC VOLTAGE CONVERTER  DESCRIPTION UTC UTL7660 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 frequency can be decreased by adding an external capacitor to the oscillator (OSC) terminal.  FEATURES * Converts +5V Logic supply to ±5V double-phase electrical Voltage * Wide input voltage range: 1.5V~10V * Efficient voltage conversion: 99.
