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 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).
