It uses current-mode control with an integrated 3A\/25V N-channel MOSFET. The 0.8V feedback reference is lower than the typical 1.2V, reducing the resistor divider current and improving light-load efficiency. The PGOOD (Power-Good) output is an open-drain pin that pulls LOW when the output voltage is outside +\/-8% of the target, useful for sequencing and reset generation. The EN pin (active HIGH, internal 1M-ohm pull-up) allows start-up when left floating. The 650kHz switching frequency provides a good balance between efficiency (91% peak) and inductor size (4.7uH typical). The current-mode architecture provides inherent cycle-by-cycle current limiting at 3.8A and stable operation with ceramic output capacitors (no external compensation required). The internal soft-start ramps the reference voltage over 2ms, limiting inrush current. The device enters pulse-skipping mode at light loads (<100mA) to maintain efficiency above 70% even at 1mA load. Operating temperature range is -40C to +125C (junction).","pin_description":"
