产品介绍

Product index

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 Protection (OCP) with High / Low Line Compensation. Therefore it can protect the system from damage due to occasional failure. The LD7790 is available in a SOP-16 package.
