Switching Regulator Controllers for DC/DC Converters

Description

The HA17451 is a dual-channel switching regulator controller IC. Each channel contains the basic circuits

for controlling a PWM-type switching-regulator power supply. Both channels are integrated onto the same

chip. Both channels can be completely synchronized, using the same oscillator output waveform. Each

channel can provide output voltages for step-up, step-down, inverting, and other converter topologies.

These controllers operate at voltages from 3.3 V to 40 V, making them suitable for a wide range of

applications. They are ideal for chopper-type DC/DC converters. They are similar to the TL1451, but note

that the HA17451A differs from the TL1451A.

Functions

•

Low-dropout 2.5V voltage reference

Undervoltage lockout

Triangle-wave oscillator

Adjustable dead-time control

Error amplifier

Output driver (open-collector transistor type)

PWM comparator
