TPS628601 - Texas Instruments

TPS628601 0.6-/1-A Synchronous Step-Down Converter

The TPS6286x devices are high-frequency, synchronous step-down converters with I2C- and VSEL-Interface. The devices provide an efficient, flexible, and high-power density point-of-load DC/DC design. 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 t.
