LD9162K - Leadtrend

LD9162K Primary Side Quasi-Resonant Controller

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 LD.
