MB3881 Datasheet (Fujitsu Media Devices)

MB3881, 8-ch DC/DC Converter

The MB3881 a step-up/step-down type of 8-channel, DC/DC converter IC.

It uses pulse width modulation (PWM) and synchronous rectification, designed for low voltage, high efficiency, and compactness.

This IC is ideal for down conversion and up/down conversion (employing a step-up/step-down Zeta system

MB3881 Features
