NCP1034 DC to DC Buck Converter Circuit Diagram and Datasheet
known to be high voltage, high power and high efficiency buck
converter. A voltage mode PWM controller for a high synchronous buck.
According to the datasheet, this buck converter features low output
voltage ripple, ceramic capacitors, over current protection, and under
The schematic diagram shows NCP1034 demo board which is designed with many options. You can see such a linear regulator which has function for powering the IC with Zener diode, compensation circuit of second or third type, ceramic or electrolytic output capcitors and various input capacity.
And here is the NCP1034 datasheet(source:onsemi.com).
