General Description
The ST1PS03 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.
Key Features
- 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.
- Selectable.
