MB3775 - SWITCHING REGULATOR CONTROLLER

Datasheet Summary

Description

1.

The reference voltage circuit generates a stable, temperature-compensated 2.5 V reference from Vcc (pin 9) for use by internal circuits.

A reference voltage of temperature compensated 1/2 Vref can be obtained to external circuit by Vref terminal (pin 16).

FUJITSU SEMICONDUCTOR DATA SHEET DS04-27204-3E ASSP SWITCHING REGULATOR CONTROLLER MB3775 LOW VOLTAGE DUAL PWM SWITCHING REGULATOR CONTROLLER The MB3775 is a dual pulse-width-modulation control circuit. It contains the basic circuits required for two PWM control circuits. Complete synchronization is obtained by using the same oscillator output waveform. This IC can provide following types of output voltage: step down, step up, and inverter. Power consumption is low, thus the MB3775 is ideal for use in highefficiency portable equipment. (DIP-16P-M04) • • • • • • • Wide supply voltage range: 3.6 V to 18 V Low current consumption: 1.
