8 V / 300 mA C2 10 mF (Fixed Output Voltage Version) 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 SO...
