HIGH-EFFICIENCY, SOT23
STEP-DOWN, DC-DC CONVERTER
High Efficiency Synchronous Step-Down
The TPS6220x devices are a family of high-efficiency
Converter With up to 95% Efficiency
synchronous step-down converters ideally suited for
2.5-V to 6-V Input Voltage Range
portable systems powered by 1-cell Li-Ion or 3-cell
Adjustable Output Voltage Range From 0.7 V
NiMH/NiCd batteries. The devices are also suitable
to VI
to operate from a standard 3.3-V or 5-V voltage rail.
Fixed Output Voltage Options Available
With an output voltage range of 6 V down to 0.7 V
Up to 300 mA Output Current
and up to 300 mA output current, the devices are
ideal to power low voltage DSPs and processors
1-MHz Fixed Frequency PWM Operation
used in PDAs, pocket PCs, and smart phones.
Highest Efficiency Over Wide Load Current
Under nominal load current, the devices operate with
Range Due to Power Save Mode
a fixed switching frequency of typically 1 MHz. At
15-A Typical Quiescent Current
light load currents, the part enters the power save
mode operation; the switching frequency is reduced
Soft Start
and the quiescent current is typically only 15 A;
100% Duty Cycle Low-Dropout Operation
therefore, it achieves the highest efficiency over the
Dynamic Output-Voltage Positioning
entire load current range. The TPS6220x needs only
three small external components. Together with the
Available in a 5-Pin SOT23 Package
SOT23 package, a minimum system solution size is
achieved. An advanced fast response voltage mode
control scheme achieves superior line and load
