Mitsubishi M62212P, M62212GP, M62212FP Datasheet

MITSUBISHI SEMICONDUCTORS <Standard Linear ICs>
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 ~ 18V
• Low power consumption••••••••••••••••••••••••1.3mA typ
• High speed switching is possible.(300kHz)
• Output short protection circuit and ON/OFF control are used. The dead-time control and the soft-start operation are possible
• Package variation : 8pin DIP/SOP/SSOP8
