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. Under nominal load current, the
devices operate with a fixed switching frequency of typically 1.25 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 mA; therefore, the device achieves the highest efficiency over the entire load current
range. The TPS6222x needs only three small
external components. Together with the tiny TSOT23
package, a minimum system solution size can be
achieved. An advanced fast response voltage mode
control scheme achieves superior line and load regulation with small ceramic input and output
capacitors.
