MB39A102 Datasheet | Fujitsu Semiconductor Limited

FUJITSU SEMICONDUCTOR DATA SHEET DS04-27232-3E ASSP For Power Management Applications (DC/DC Converter for DSC/Camcorder) 4-ch DC/DC Converter IC - 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. - Features - - - - - - - - - Supports for down-conversion and up/down Zeta conversion (CH1 to CH3) Supports for up-conversion and up/down Sepic conversion (CH4) Power supply voltage range : 2.5 V to 11 V Reference voltage : 2.0 V ± 1 % Error amplifier threshold voltage : 1.24 V ± 1.5 % Built-in totem-pole type output for MOS FET Built-in soft-start circuit without load dependence High-frequency operation capability : 1.5 MHz (Max) External short-circuit detection capability by - INS terminal - PACKAGES 30-pin plastic TSSOP 32-pad plastic BCC (FPT-30P-M04) (LCC-32P-M15) .. .. - PIN ASSIGNMENTS (TOP VIEW) CS2 - INE2 FB2 DTC2 VCC CTL VREF RT CT GND CSCP DTC3 FB3 - INE3 CS3 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 CS1 - INE1 FB1 DTC1 VCCO OUT1 OUT2 OUT3 OUT4 GNDO - INS DTC4 FB4 - INE4 CS4 (FPT-30P-M04)...
