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.
