Overview

LD7790 9/11/2013 Transition-Mode PFC and Quasi-Resonant Current Mode PWM Controller REV: 00 General Description The LD7790 features transition mode Power Factor correction (PFC) controller and Quasi-Resonant (QR) current mode controller for cost effective and fewer external components design of high power application.
The intelligent PFC switching ON/OFF, zero current detection (ZCD) and frequency limitation mechanism enable a better efficiency under any load conditions.
The device is also integrated several functions of protection, such as X-CAP discharge, Brown-in/out protection, Over Load protection (OLP), Over Temperature Protection (OTP), Over Voltage Protection (OVP) and Over Current...
