Product overview
Description
This converter is specifically designed for applications where high efficiency, PCB size and thickness are the key factors. The output voltage can be set using two digital control inputs, a VOUT from 0.625 V to 3.3 V can be dynamically selected. Thanks to the enhanced PCC (peak current control) the ST1PS01 reaches very high efficiency conversion using just a 2.2 µH inductor and two small capacitors. Advanced design circuitry is implemented to minimize the quiescent current. The device is available in Flip-Chip package.-
All features
- 500 nA input quiescent current at VIN=3.6 V (not switching)

- 1.8 V to 5.5 V input operating range
- Undervoltage lockout: 1.57 V (VIN falling, typ.)
- Up to 400 mA output current capability
- Low power control operation for the best efficiency
- Embedded soft-start circuit
- Tiny external components: L=2.2 µH typ.
- Selectable output voltages: 0.625 V to 3.3 V
