ST1PS02 400mA nano-quiescent synchronous step-down converter

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 fac.

ST1PS02 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 m
