Overview
The NCP12700 is a fixed frequency, peak current mode, PWM controller containing all of the features necessary for implementing single−ended power converter topologies. The device features an ultra−wide range, high voltage startup regulator capable of regulating VCC across an input voltage range of 9 - 120 V (xDNR2G) or 9 - 200 V (xMTTXG). The controller is designed for high speed operation including a programmable oscillator capable of operating from 100 kHz to 1 MHz and total propagation delays less than 75 ns in the PWM path. The NCP12700 integrates slope compensation to prevent subharmonic oscillations and an Input Voltage Compensation / Over−Power Protection (OPP) feature that limits the converter power delivery capability across input voltage, easing system thermal design. The controller offers an adjustable soft−start, input voltage UVLO protection, and a suite of protection features including cycle−by−cycle current limit and a FLT pin with a NTC interface for system thermal protection. The UVLO pin also features a shutdown comparator which allows for an externally applied pull−down signal to disable switching and bring the controller into a low quiescent state.
