ME 7660
ME7660 Charge Pump DC-DC
Voltage Converter
Introduction Me7660 is a charge pump dc-to-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 po...
