Texas Instruments  TPS62250DRVT

The TPS62250 device is a high efficient synchronous step down dc-dc converter optimized for USB powered applications. It provides up to 1A peak output current and limits the average input current to 700mA, making it ideal for applications connected to a USB host. With an wide input voltage range of 2V to 6V, the device supports applications powered by the USB host as well as general applications requiring large output capacitors.

The TPS62250 operates at 2.25MHz fixed switching frequency and enters Power Save Mode operation at light load currents to maintain high efficiency over the entire load current range.

The Power Save Mode is optimized for low output voltage ripple.

The TPS62250 is available in a very small 2×2 6 pin SON package.
