MB39A103 - Fujitsu

MB39A103 4-Channel DC/DC Converter IC

The MB39A103 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. Achievement of low voltage start-up (1.7 V or more) enables operation from low voltage. 4ch is built in TSSOP-30P/package. Each channel can be controlled, and soft-start. This is an ideal power supply.
