LD9162K 03/10/2021 Primary Side Quasi-Resonant Controller with MOSFET Integrated REV. 00 General Description The LD9162K is an excellent primary-side feedback controller with QR operation, integrated with a 650V MOSFET switch in a SOP-8 package. It minimizes the components counts and is ideal for low cost applications. It provides functions of ultra-low startup current, green-mode power-saving operation and leading-edge blanking of the current sensing. Also, the LD9162K includes the comprehensive protection function, such as Over Load Protection (OLP), Over Voltage Protection (OVP), and internal Over Temperature Protection (OTP). Furthermore, the programmable brown-in/out protection and bulk cap. OVP protection is built-in.
