6 ch DC/DC Converter IC with

Synchronous Rectification

MB39A123

■

DESCRIPTION

MB39A123 is a 6-channel DC/DC converter IC using pulse width modulation (PWM) , and it is suitable for up

conversion, down conversion, and up/down conversion. MB39A123 is built in 6 channels into BCC-48++/LQFP-

48P package and this IC can control and soft-start at each channel. MB39A123 is suitable for power supply of

high performance potable instruments such as a digital still camera (DSC).

■
