Description

The TPS62230, TPS6223X device family is a high frequency synchronous step down DC-DC converter optimized for battery powered portable applications. It supports up to 500mA output current and allows the use of tiny and low cost chip inductors and capacitors.

With a wide input voltage range of 2.05V to 6V the device supports applications powered by Li-Ion batteries with extended voltage range. The minimum input voltage of 2.05V allows as well the operation from Li-primary or two alkaline batteries. Different fixed output voltage versions are available from 1.0V to 3.3V.
