The TPS6286Axx and TPS6286Bxx devices are high-frequency, synchronous, step-down converters which provide an efficient, flexible, and high power-density design. At medium to heavy loads, the converters operate in pulse width modulation (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 the DCS-Control architecture, excellent load transient performance and tight output voltage accuracy is achieved. The devices feature a Power-Good signal and an adjustable soft-start feature. 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.
