TPS628680CRQY 4-A/6-A Synchronous Step-Down Converter

The TPS62868 and TPS62869 devices are highfrequency synchronous step-down converters with I2C interface which provide an efficient, adaptive, and high power-density solution. At medium to heavy loads, the converter operates in PWM mode and automatically enters Power Save Mode operation at light load to maintain high efficiency over the entire load current r.
