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
