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.
Feature
• Wide operation power supply voltage range…….. 2.5 to 18 V
• Low power consumption…….……..…….……… 1.3 mA typ
• High speed switching is possible (300 kHz).
• Output short protection circuit and ON/OFF control are used.
The dead-time control and the soft-start operation are possible
• Package variation: 8-pin DIP/SOP/SSOP8
Applications
General electric products, DC/DC converter
