The PT5071 is a 1.5 ampere rated step-up/step-down Integrated Switching Regulator (ISR) that provides a tightly regulated 12V output voltage from a 7V to 16V variable input source. This high-performance ISR has applications in systems where the input voltage straddles the desired 12V output. The regulator has an adjustable output voltage and input start-up threshold, and a standby function for power conservation.
The document describes the PT5071, a single-device integrated switching regulator rated for 1.5 amperes with a +12V output and an input voltage range of 7V to 16V. It features high efficiency (up to 84%) and includes adjustable output voltage and undervoltage lockout functions.
