3 Description

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 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 300 mA output current, the devices are

ideal to power low voltage DSPs and processors

used in PDAs, pocket PCs, and smart phones. Under nominal load current, the devices operate with a fixed

switching frequency of typically 1 MHz. At light load

currents, the part enters the power save mode

operation; the switching frequency is reduced and the

quiescent current is typically only 15 μA; therefore, it achieves the highest efficiency over the entire load

current range. The TPS6220x needs only three small

external components. Together with the SOT23

package, a minimum system solution size is

achieved. An advanced fast response voltage mode control scheme achieves superior line and load

regulation with small ceramic input and output

capacitors.
