Description

General part information

TPS62240 Series

The TPS6224x device is a highly efficient synchronous step-down DC-DC converter. The device provides up to 300-mA output current from a single Li-Ion cell and is ideal for battery powered portable applications like mobile phones and other portable equipment.

With an wide input voltage range of 2 V to 6 V, the device also supports two- and three-cell alkaline, 3.3-V and 5-V input voltage rails.

The TPS6224x operates at 2.25-MHz fixed switching frequency and enters power save mode operation at light load currents to maintain high efficiency over the entire load current range.
