Overview
FUJITSU SEMICONDUCTOR DATA SHEET DS04-27232-3E ASSP For Power Management Applications (DC/DC Converter for DSC/Camcorder) 4-ch DC/DC Converter IC MB39A102 ■ DESCRIPTION The MB39A102 is a 4-channel DC/DC converter IC using pulse width modulation (PWM).
This IC is ideal for up conversion, down conversion, and up/down conversion.
4ch is built in TSSOP-30P/BCC-32P package.
Each channel can be controlled, and soft-start.
This is an ideal power supply for high-performance portable devices such as digital still cameras.
