1 Features 3 Description

 devices are a family of high-efficiency 1• High-Efficiency Synchronous Step-Down

synchronous step-down converters ideally suited for Converter With up to 95% Efficiency portable systems powered by 1-cell Li-Ion or 3-cell

• 2.5-V to 6-V Input Voltage Range NiMH/NiCd batteries. The devices are also suitable to

• Adjustable Output Voltage Range From 0.7 V to VI 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. Under

• Highest Efficiency Over Wide Load Current Range nominal load current, the devices operate with a fixed

Due to Power Save Mode switching frequency of typically 1 MHz. At light load

• 15-μA Typical Quiescent Current currents, the part enters the power save mode

• Soft Start operation; the switching frequency is reduced and the

• 100% Duty Cycle Low-Dropout Operation achieves the highest efficiency over the entire load

• Dynamic Output-Voltage Positioning current range. The TPS6220x needs only three small

• Available in a 5-Pin SOT23 Package external components. Together with the SOT23

package, a minimum system solution size is
