TPS62290DRVTG4 Datasheet PDF - TI

Description

●The TPS6229x devices are highly efficient synchronous step down DC/DC converters optimized for battery powered portable applications. They provide up to 1000-mA output current from a single Li-ion cell.

●With an input voltage range of 2.3 V to 6.0 V, the devices support batteries with extended voltage range and are ideal to power portable applications like mobile phones and other portable equipment.

●The TPS6229x devices operate at 2.25-MHz fixed switching frequency and enter power save mode operation at light load currents to maintain high efficiency over the entire load current range.
