The TPS62865 and TPS62867 devices are high-frequency 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 can also be forced in PWM mode operation to minimize output voltage ripple. Together with its DCS-control architecture, excellent load transient performance and tight output voltage accuracy are achieved. The devices feature a Power Good signal and an internal soft start circuit. The devices are able to operate in 100% mode. For fault protection, the devices incorporate a HICCUP short circuit protection as well as a thermal shutdown.
