ADP2109 - Step-Down Converter

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.

Features

  • Peak efficiency: 95% Discharge switch function Fixed frequency operation: 3 MHz Typical quiescent current: 18 μA Maximum load current: 600 mA Input voltage: 2.3 V to 5.5 V Uses tiny multilayer inductors and capacitors Current mode architecture for fast load and line transient response 100% duty-cycle low dropout mode Internal synchronous rectifier Internal compensation Internal soft start Current overload protection Thermal shutdown protection Shutdown supply current: 0.2 μA 5-ball WLCSP Support.
