Thick Film Hybrid IC
3.3V/5A Single Output Separate Excitation Chopper Regulator
Overview
The STK740-441 is a separate-excitation step-down chopper regulator hybrid IC for the secondstage circuit and optimal as a 3.3V local power supply for use in logic circuit that includes both 5V and 3.3V systems. This IC incorporates in the package all the necessary circuits for a chopper regulator including power switch, error amplifier, soft start, shutdown type output short protection, low-voltage malfunction prevention, on/off, and snubber circuits. Therefore, external ponents required are input and output capacitors and choke coil only and this allows this IC...
