The STMicroelectronics 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

Output voltage power good

±1.5% output voltage accuracy (VOUT, TA = 25 °C)

Dynamic output voltage selection (D0, D1 and D2)

Load switch controlled by AUX input

Available in TQFN12 package
