Overview
FUJITSU MICROELECTRONICS DATA SHEET DS04-27237-2Ea ASSP for Power Supply Applications (DC/DC converter for DSC/camcorder) 5 ch DC/DC Converter IC with Synchronous Rectification MB39A108 ■ DESCRIPTION The MB39A108 is 5-channel DC/DC converter IC using pulse width modulation (PWM), and is suitable for up conversion, down conversion, and up/down conversion.
The MB39A108 is built in 5 channels into TSSOP-38P/ BCC-40P package and operates at 2 MHz maximum.
Each channel can be controlled with soft-start.
The MB39A108 is suitable for power supply of high performance portable instruments such as DSC.
■ FEATURES • Supports for down-conversion with synchronous rectification (CH1) • Supports for down-conversion and up/down Zeta conversion (CH2, CH3) • Supports for up-conversion and up/down Sepic conversion (CH4, CH5) • Low voltage start-up (CH4, CH5) : 1.
7 V • Power supply voltage range : 2.
5 V to 11 V • Reference voltage : 2.
0 V ± 1% • Error amplifier threshold voltage : 1...
