 General Description
The ML63S is a group of PFM Step-up DC/DC
converter IC with low supply current by CMOS
process.
It consists of an oscillator, a PFM control circuit, a
Lx switch driver transistor, a reference voltage unit,
an error amplifier for voltage detection and a Lx
switch protection circuit. It is suitable for use with
battery-powered instruments with low noise and
low supply current.
