HA17451AP/HA17451AFP
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
