NCP12711 - PWM Controller

Description

The UVLO pin is the input to the standby and UVLO comparators.

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 to.

DATA SHEET www.onsemi.com Current Mode PWM Controller NCP12711 The NCP12711 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.
