General 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.

The buck regulator automatically switches operating modes, depending on the load current level, to maximize efficiency.

Key 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.
