ST1PS03
Overview
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. This converter is specifically designed for applications where high efficiency, PCB size and thickness are the key factors.
- 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 output voltages: 1.6 V to 3.3 V
