2.25MHz 1A Step-Down Converter in 2x2mm SON Package - TPS62290

TPS62290 (ACTIVE)

2.25MHz 1A Step-Down Converter in 2x2mm SON Package

Description

The TPS6229x device is a higly efficient synchronous step down dc-dc converter optimized for battery powered portable applications. It provides up to 1000-mA output current from a single Li-Ion cell.

With an input voltage range of 2.3 V to 6 V, the device supports batteries with extended voltage range and are ideal to power portable applications like mobile phones and other portable equipment.

The TPS6229x operates at 2.25-MHx 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. For low noise applications, the device can be forced into fixed fequency PSM mode by pulling the MODE pin high. In the shutdown mode the current consumption is reduced to less than a µA. The TPS6229x allows the use of small inductors and capacitors to acieve a small solution size.

The TPS6229x is available in a 2-mm x 2-mm 6-pin SON package.
