TPS62207

The TPS6220x 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 TPS6220x is also suitable to operate from a standard 3.3-V or 5-V voltage rail.

With an output voltage range of 6.0 V down to 0.7 V and up to 300 mA output current, the TPS6220x is ideal to power low voltage DSPs and processors used in PDAs, pocket PCs, and smart phones.  the part enters the power save mode operation; the switching frequency is reduced and the quiescent current is typically only 15 A; therefore TPS6220x achieves the highest efficiency over the entire load current range. The TPS6220x needs only three small external components. Together with the tiny SOT23 package, a minimum system solution size can be achieved. An advanced fast response voltage mode control scheme achieves superior line and load regu- lation with small ceramic input and output capacitors.
