 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.
