LD7791
Description
The LD7791 features transition mode Power Factor correction (PFC) controller and Quasi-Resonant (QR) current mode controller for cost effective and fewer external ponents 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 pensation. Therefore it can protect the system from being damaged due to occasional failure.
The LD7791 is available in a SOP-16 package.
