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.
Key Features
- 500 nA input quiescent current at VIN=3.6 V (not switching)
- 94% typical efficiency at 1 mA load (VIN=3.6 V, VOUT=3.3 V)
- 100% duty cycle
- 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
- Output voltage Power Good
- ±1.5% output voltage accuracy (VOUT, TA = 25 °C)
- Dynamic output voltage selection (D0, D1)
- Available in Flip-Chip package
