FUJITSU SEMICONDUCTOR DATA SHEET DS04-27237-2E 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 : 1.00 V ± 1% (CH1), 1.23 V ± 1% (CH2 to CH5) - Oscillation frequency range : 200 k Hz to 2.0 MHz .. - Standby current : 0 µA (Typ) - Built-in soft-start circuit independent of loads - Built-in totem-pole type output for MOS FET - Short-circuit detection capability by external signal ( - INS terminal) - Two types of package (TSSOP-38 pin : 1 type, BCC-40 pin : 1 type) - APPLICATIONS - Digital still camera (DSC) - Digital video camera (DVC) - Surveillance camera etc. Copyright©2005-2006 FUJITSU LIMITED All rights reserved MB39A108 - PIN...
