MB39A106 - 2-Channel DC/DC Converter IC

General Description

The MB39A106 is a symmetrical-phase type of two-channel, DC/DC converter IC using pulse width modulation (PWM) , incorporating an overcurrent protection circuit (requiring no current sense resistor) and an overvoltage protection circuit.

Key Features

  • which output the protection status upon detection of an overvoltage or overcurrent while reducing the number of external protective devices required. The result is an ideal built-in power supply for driving products with high speed CPU’s such as home TV game devices and notebook PC’s. s.

FUJITSU SEMICONDUCTOR DATA SHEET DS04-27235-1E ASSP For Power Supply Applications (General Purpose DC/DC Converter) 2-Channel DC/DC Converter IC with Overcurrent Protection Symmetrical-Phase Type MB39A106 s DESCRIPTION The MB39A106 is a symmetrical-phase type of two-channel, DC/DC converter IC using pulse width modulation (PWM) , incorporating an overcurrent protection circuit (requiring no current sense resistor) and an overvoltage protection circuit. Providing high output driving capabilities, the MB39A106 is suitable for down-conversion. The MB39A106 adopts both synchronous rectification to provide high efficiency and symmetrical phasing (two anti-phase triangular waves) which contributes to making the input capacitor small.
