Overview
FUJITSU SEMICONDUCTOR DATA SHEET DS04-27230-3E ASSP For Power Manegement Applications (DC/DC Converter for DSC/Camcorder) 4-ch DC/DC Converter IC for low voltage MB39A103 ■ DESCRIPTION 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 for high-performance portable devices such as digital still cameras.
This product is covered by US Patent Number 6,147,477.
■ FEATURES • • • • • • • • • • Supports for down-conversion and up/down Zeta conversion (CH1) Supports for up-conversion and up/down Sepic conversion (CH2 to CH4) Low voltage start-up (CH4): 1.
7 V Power supply voltage range : 2.
5 V to 11 V Reference voltage : 2.
