General Description
The ML65 is a group of PWM Step-up DC/DC
converter IC with ultra-low supply current by
CMOS process.
It consists of an oscillator, a PWM control circuit, a
Lx switch driver transistor, a reference voltage unit,
an error amplifier for voltage detection and an Lx
switch protection circuit. It is suitable for use with
battery-powered instruments with low noise and
ultra low supply current.
