Overview
The NCP3063PG, produced by onsemi, is a versatile Power Management IC (PMIC) designed for DC-DC switching regulation. It is an upgraded version of the popular MC34063A and MC33063A monolithic DC-DC converters, offering higher frequency operation. This device is capable of stepping up or stepping down voltage levels with adjustable output, making it suitable for a wide range of applications.
The NCP3063PG supports both Buck and Boost topologies, as well as voltage-inverting configurations, with a minimum number of external components. It features an internal temperature-compensated reference, a comparator, a controlled duty cycle oscillator, an active current limit circuit, a driver, and a high current output switch.
