Summary
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.
