General Description

The ADP2109 is a high efficiency, low quiescent current stepdown dc-to-dc converter with an internal discharge switch that allows automatic discharge of the output capacitor in an ultrasmall 5-ball WLCSP package.

The total solution requires only three tiny external components.

It uses a proprietary high speed current mode and constant frequency pulse-width modulation (PWM) control scheme for excellent stability, and transient response.
