Microchip, MIC4576WU Switching Regulator, 1-Channel 3A Adjustable 5-Pin, D2PAK

The MIC4575 is a series of easy to use fixed and adjustable BiCMOS step-down (buck) switch-mode voltage regulators. The 200kHz MIC4575 duplicates the pinout and function of the 52kHz LM2575. The higher switching frequency may allow up to a 2:1 reduction in output filter inductor size.Fixed version: ±3% max. output voltage Adjustable version: ±2% max. feedback voltage Guaranteed 1A switch current Fixed 200kHz operation 3.3V, 5V, and adjustable output versions Voltage over specified line and load conditions: Fixed version: ±3% max. output voltage Adjustable version: ±2% max. feedback voltage Guaranteed 1A switch current Wide input voltage range: 4V to 24V Wide output voltage range: 1.23V to 20V Requires minimum external components < 200μA typical shutdown mode 75% efficiency (adjustable version > 75% typical) Standard inductors and capacitors are 25% of typical LM2575 values. Thermal shutdown Overcurrent protection 100% electrical thermal limit burn-in
