MB3889 - 2-Channel DC/DC Converter IC

Description

The MB3889 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.

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. This product is covered by US Patent Number 6,147,477. s.

Providing high output driving capabilities, the MB3889 is suitable for down-conversion. The MB3889 adopts both synchronous rectification to provide high efficiency and symmetrical phasing (two antiphase triangular waves) which contributes to making the input capacitor small.
