M62210FP
GENERAL PURPOSE MULTI FUNCTION DC-DC CONVERTER
Notice: This is not a final specification. Some parametric limits are subject to change.
DESCRIPTION
M62210FP is designed as a general purpose multi-function 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 pact set design. 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.

FEATURE
Wide operation power supply voltage range…………2.5~18V Low power consumption ………………………………1.3mA typ 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) 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.
