Description

The MB39A102 is a 4-channel DC/DC converter IC using pulse width modulation (PWM). This IC is ideal for up onversion, down conversion, and up/down conversion. 4ch is built in TSSOP-30P/BCC-32P package. Each channel can be controlled, and soft-start. The MB39A102 is an ideal power supply for high-performance portable devices such as digital still cameras
