onsemi NCV12711 DC-DC Converter, 4 → 45 V dc Input

The ON Semiconductor NCV series of a fixed frequency peak current mode PWM controller containing all of the features necessary for implementing single-ended power converter topologies. The device operates from 4 V to 45 V without auxiliary winding and within its thermal capabilities. The controller contains a programmable oscillator capable of operating from 100 kHz to 1 MHz and integrates slope compensation to prevent subharmonic oscillations.
