LD9162K
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 ponents 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 prehensive 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. In most cases, PSR controlled flyback converters would suffer from bad load regulation performance. To deal with this problem, dedicated load regulation pensation is also implemented in LD9162K.
