Description: Step-Down Converter

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-cycl

Applications

* the ADP2109 has a power save mode that reduces the switching frequency under light load conditions. The ADP2109 runs on input voltages of 2.3 V to 5.5 V, which allow for single lithium or lithium polymer cell, multiple alkaline or NiMH cells, PCMCIA, USB, and other standard power sources.
