M62212P/FP/GP
General Purpose DC/DC Converter
Description
M62212 is designed as a general purpose DC/DC converter.
This small 8-pin package contains many functions allowing simpler peripheral circuits and compact set design.
The output transistor is open collector and emitter follower type. This makes the control STEP-UP, STEP-DOWN and
INVERTING converter.
