General Description

The TPS6222x devices are a family of high-efficiency, synchronous step-down converters ideally suited for portable systems powered by 1-cell Li-Ion or 3-cell NiMH/NiCd batteries.

The devices are also suitable to operate from a standard 3.3-V or 5-V voltage rail.

With an output voltage range of 6 V down to 0.7 V and up to 400-mA output current, the devices are ideal for powering the low voltage TMS320™ DSP family and processors used in PDAs, pocket PCs, and smart phones.
