MB3778 - Switching Regulator Controller

Datasheet Summary

Description

The MB3778 is a dual switching regulator control IC.

It has a two-channel basic circuit that controls PWM system switching regulator power.

Complete synchronization is achieved by using the same oscillator output wave.

Features

  • Wide input voltage range : 3.6 V to 18 V Low current consumption : 1.7 mA typ. operation, 10 µA max. stand-by Wide oscillation frequency range:1 kHz to 500 kHz Built-in timer latch short-circuit protection circuit Built-in under-voltage lockout circuit Built-in 2.46 V reference voltage circuit : 1.23 V output can be obtained from RT terminal Variable dead-time provides control over total range Built-in stand-by funct.

FUJITSU SEMICONDUCTOR DATA SHEET DS04-27203-6E ASSP Switching Regulator Controller MB3778 s DESCRIPTION The MB3778 is a dual switching regulator control IC. It has a two-channel basic circuit that controls PWM system switching regulator power. Complete synchronization is achieved by using the same oscillator output wave. This IC can accept any two of the following types of output voltage: step-down, step-up, or voltage inversion (inverting voltage can be output to only one circuit). The MB3778’s low power consumption makes it ideal for use in portable equipment. s FEATURES • • • • • • • • Wide input voltage range : 3.6 V to 18 V Low current consumption : 1.7 mA typ. operation, 10 µA max.
