ADP2147 - Buck Regulator

Datasheet Summary

Description

The ADP2147 is a high efficiency, low quiescent current, stepdown (buck) dc-to-dc regulator with an output voltage that can be switched between two different settings under the control of a select pin.

The total solution requires only three tiny external components.

Features

  • Input voltage: 2.3 V to 5.5 V Peak efficiency: 95% 3 MHz fixed frequency operation Low quiescent current: 23 μA Ultralow shutdown current: 0.2 μA (typical) VSEL pin for simple dynamic voltage scaling (DVS) 100% duty cycle low dropout mode Internal synchronous rectifier, compensation, and soft start Current overload and thermal shutdown protection Small, 6-ball, 1 mm × 1.5 mm WLCSP package.
