Description

The TPS62240 device is a high efficiency synchronous step down dc-dc converter optimized for battery powered portable applications. It provides up to 300 mA output current from a single Li-Ion cell and is ideal to power portable applications like mobile phones and other portable equipment.

With an input voltage range of 2 V to 6 V, the device supports applications powered by Li-Ion batteries with extended voltage range, two- and three-cell alkaline, 3.3-V and 5-V input voltage rails.

The TPS62240 operates at 2.25 MHz 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.
