Ordering number:EN6106 Thick Film Hybrid IC STK740-441 3.3V/5A Single Output Separate Excitation Chopper Regulator Overview Package Dimensions The STK740-441 is a separate-excitation step-down unit:mm chopper regulator hybrid IC for the secondstage circuit 4171-SIP12 and optimal as a 3.3V local power supply for use in logic [STK740-441] 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 4.5 37.0 amplifier, soft start, shutdown type output short protec- tion, low-voltage malfunction prevention, on/off, and snubber circuits. Therefore, external components re- quired are input and output capacitors and choke coil only and this allows this IC to be used to cons
