ADP2119 Overview
The ADP2119/ADP2120 are low quiescent current, synchronous, step-down dc-to-dc regulators in a pact 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...
