DESCRIPTION
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●
