TPS62867 - Texas Instruments

TPS62867 4-A and 6-A Synchronous Step-Down Converter

The TPS62865 and TPS62867 devices are highfrequency synchronous step-down converters which provide an efficient, flexible, and high power-density solution. At medium to heavy loads, the converters operate in PWM mode and automatically enter Power Save Mode operation at light load to maintain high efficiency over the entire load current range. The devices ca.
