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.
