ADP2118

GENERAL DESCRIPTION

The ADP2118 is a low quiescent current, synchronous, step-down

dc-to-dc regulator in a compact 4mm × 4mm LFCSP package. It

uses a current mode, constant frequency pulse-width modulation

(PWM) control scheme for excellent stability and transient

response. Under light loads, the ADP2118 can be configured to

operate in pulse frequency modulation (PFM) mode that

reduces switching frequency to save power.

The ADP2118 runs from input voltages of 2.3 V to 5.5 V. The

output voltage of the ADP2118ACPZ-R7 is adjustable from

0.6 V to input voltage (V

), and the ADP2118ACPZ-x.x-R7 are

available in preset output voltage options of 1.2 V and 3.3 V.

The ADP2118 requires minimal external parts and provides a high

efficiency solution with its integrated power switch, synchronous

rectifier, and internal compensation. The IC draws less than 3 µA

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 (OCP), and thermal shutdown (TSD).
