M62210FP
GENERAL PURPOSE MULTI FUNCTION DC-DC CONVERTER
Notice: This is not a final specification.
DESCRIPTION
Some parametric limits are subject to change.
M62210FP is designed as a general purpose multi-function
PIN CONFIGURATION(TOP VIEW)
DC-DC converter. This is most suitable as a back-light control
for a LCD,etc.
This small 10 pin package contains many functions allowing
simpler peripheral circuits and compact set design.
Collector
output ¹
10 VCC
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.

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.(300kHz)
OUTLINE 10P2
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.
APPLICATIONS
Back-light control of personal computers and word processors
General electric products
