HA17451AP Switching Regulator Controllers for DC/DC Converters

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 wavef.
