ME7660
CHARGE PUMP DC-DC
VOLTAGE CONVERTER
DESCRIPTION
ME7660
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 below 10 KHZ (for lower supply current
applications) is possible by connecting an external capacitor from OSC
to ground.
