ST1PS03 Product details

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.

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.
