GENERAL DESCRIPTION
The ADP2102 is a low quiescent current step-down DC-DC converter optimized to regulate low output voltages in a compact 3mmx3mm LFCSP package. At high load currents, the ADP2102 uses a current mode, constant on time, pseudo fixed frequency, valley current control scheme for excellent stability and transient response with very few, small external components. To ensure the longest battery life in portable applications, the ADP2102 has a power saving mode that reduces the switching frequency under light load conditions to significantly reduce the quiescent current.
