M62211P/FP
GENERAL PURPOSE MULTI FUNCTION DC-DC CONVERTER
DESCRIPTION
M62211FP is designed as a general purpose multi-function
DC-DC converter. This small 10 pin package contains many
functions allowing simpler peripheral circuits and compact set
design.
The output circuit is designed OPEN-COLLECTOR output.
This makes the application for STEP-UP, STEP-DOWN and
INVERTING.
The input of this unit has two channels containing priority
control circuit. This makes the control a simple matter when
the back-light is on and during the stable state.
Notice: This is not a final specification.
Some parametric limits are subject to change.

FEATURE
• Wide operation power supply voltage range•••••••2.5~35V
• Operation can be synchronized by the external sync signal
• Operation can be controlled using two prioritized systems.
(High input has priority)
• High speed switching is possible.(500kHzmax)
• Output short protection circuit and ON/OFF control are used.
The dead-time control and the soft-start operation are
possible
• Small size 10-pin SOP package.
