Product Change Notification
The NCV12711 is 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. The controller includes a programmable soft-start, input voltage UVLO protection, and an over-power protection (OPP) circuit which limits the total power capability of the circuit as the input voltage increases. The UVLO pin also features a shutdown comparator which allows for an external signal to disable switching and brings the controller into a low quiescent state. An onboard opamp allows the implementation of primary-side regulated converters or non-isolated dc-dc converters.
