Description

The PT5071 is a 1.5-ampere rated step-up/step-down Integrated Switching Regulator(ISR) that provides a tightly regulated 12Voutput voltage from a 7V to 16V variableinput source. This high-performance ISR hasapplications in systems where the inputvoltage straddles the desired 12V output.The regulator has an adjustable outputvoltage and input start-up threshold, and astandby function for power conservation.
