DESCRIPTION
The FUJITSU MB3782 is a PWM-type switching regulator controller, designed with open-collector output for
connection to external drive transistors and coils, providing a selection of three types of output voltage: step-
up, step-down or inverting (inverting output is available on one circuit only).
The MB3782 features identical oscillator output waveforms to enable completely synchronous operation and
prevent the occurrence of low-frequency beat between channels.
Also, the MB3782 features low power dissipation (2.1 mA typ) and a built-in standby mode (10
μ
A), making
possible the configuration of a wide variety of high-efficiency, stable power supplies, even with the use of battery
power. The MB3782 is an ideal power supply for high-performance portable devices such as video camcorders
and cameras.
