GENERAL DESCRIPTION

The ADP2119/ADP2120 are low quiescent current, synchronous,

step-down dc-to-dc regulators in a compact 3 mm × 3 mm

LFCSP_WD package. Both devices use a current mode, constant

frequency pulse-width modulation (PWM) control scheme for

excellent stability and transient response. Under light load conditions,

they can be configured to operate in a pulse frequency modulation

(PFM) mode, which reduces switching frequency to save power.

The ADP2119/ADP2120 support input voltages from 2.3 V to

5.5 V. The output voltage can be adjusted from 0.6 V up to the

input voltage (V

) for the adjustable version, whereas the fixed

output version is available in preset output voltage options of 3.3 V,

2.5 V, 1.8 V, 1.5 V, 1.2 V, and 1.0 V. The ADP2119/ADP2120 require

minimal external parts and provide a high efficiency solution with

their integrated power switches, synchronous rectifiers, and internal

compensation. Each IC draws less than 2 µA current from the input

source when it is disabled. Other key features include undervoltage

lockout (UVLO), integrated soft start to limit inrush current at

startup, overvoltage protection (OVP), overcurrent protection
