Data sheet:
The ST1PS02 is a nano-quiescent miniaturized synchronous step-down converter, which is able to provide up to 400 mA output current with an input voltage ranging from 1.8 V to 5.5 V. 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 three digital control inputs, a VOUT from 1.0 V to 3.3 V can be dynamically selected. Thanks to the enhanced PCC (peak current control) the ST1PS02 reaches very high efficiency conversion using just a 2.2 µH inductor and two small capacitors. The device embeds a controlled load switch to supply a subsystem with same voltage rail. Advanced design circuitry is implemented to minimize the quiescent current. The device is available in thin plastic package.
- 500 nA input quiescent current at VIN = 3.6 V (not switching)
- 92% typical efficiency at 10 mA load (VIN = 3.6 V, VOUT = 2.5 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.
- Settable inductor current limitation
- Selectable output voltages: 1.0 V to 3.3 V
- Output voltage Power Good
- ±1.5% output voltage accuracy (VOUT, TA = 25 °C)
- Dynamic output voltage selection (D0, D1 and D2)
- Auxiliary load switch Vout2 (AUX control input)
- Available in TQFN12 package
