• High Efficiency Step Down Converter

• Output Current up to 600 mA

The TPS62260 device is a high efficient synchronous

step down dc-dc converter optimized for battery

• Wide V

powered applications. It provides up to 600-mA

Batteries with Extended Voltage Range

output current from a single Li-Ion cell and is ideal to

• 2.25 MHz Fixed Frequency Operation

power mobile phones and other portable applications.

• Power Save Mode at Light Load Currents

With an wide input voltage range of 2 V to 6 V, the

• Output Voltage Accuracy in PWM mode ±1.5%

device supports applications powered by Li-Ion

batteries with extended voltage range, two and three

• Typ. 15 µA Quiescent Current

cell alkaline batteries, 3.3 V and 5 V input voltage

• 100% Duty Cycle for Lowest Dropout

rails.

• Soft Start

The TPS62260 operates at 2.25 MHz fixed switching

• Voltage Positioning at Light Loads

frequency and enters Power Save Mode operation at

• Available in a small 2×2×0,8mm SON and

light load currents to maintain high efficiency over the

TSOT-23 package

entire load current range.

• Allows <1mm Solution Height

The Power Save Mode is optimized for low output

voltage ripple. For low noise applications, the device

can be forced into fixed frequency PWM mode by

pulling the MODE pin high. In the shutdown mode,

• PDAs, Pocket PCs

the current consumption is reduced to less than 1

µA.

• Low Power DSP Supply

TPS62260 allows the use of small inductors and

• Portable Media Players

capacitors to achieve a small solution size.

• POL applications

The TPS62260 is available in a very small 2

×2 6 pin

SON and TSOT-23 5 pin package.
