LD7791 05/26/2016 Transition-Mode PFC and Quasi-Resonant Current Mode PWM Controller REV: 03 General Description The LD7791 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 it to reach better efficiency under any load conditions. The device also integrates 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 Protection (OCP) with High / Low Line Compensation.
