The ADP2109 is a high efficiency, low quiescent current step-down dc-to-dc converter with an internal discharge switch that allows automatic discharge of the output capacitor in an ultra-small 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. To ensure the longest battery life in portable applications, the ADP2109 has a power save mode that reduces the switching frequency under light load conditions.
