Overview
The NCP3063BPG, produced by onsemi, is a versatile Power Management IC (PMIC) designed for DC-DC switching regulation. It is a higher frequency upgrade to the popular MC34063A and MC33063A monolithic DC-DC converters. This device is optimized for step-up, step-down, and voltage-inverting applications, requiring a minimum number of external components. It features an internal temperature-compensated reference, comparator, a controlled duty cycle oscillator, an active current limit circuit, a driver, and a high current output switch.
