The 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.
The TPS6223X series features switch frequency up to 3.8MHz. At medium to heavy loads, the converter operates in PWM mode and automatically enters Power Save Mode operation at light load currents to maintain high efficiency over the entire load current range.
