Introduction

AI Translation

The LD7792N/O is the enhancement version of the LD7792, the audible noise produced during start-up & light load is greatly reduced and the THDi is also further improved. LD7792N/O 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 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. Therefore it can protect the system from damage due to occasional failure.
