Primary Side Quasi-Resonant BJT Controller with CV/CC Operation
REV. 00
General Description
The LD7515L is an excellent primary side feedback BJT controller with CV/CC operation, integrated with several functions of protections. It minimizes the ponent counts and is available in a tiny SOT-26 package. Those make it an ideal design 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 LD7515L Features
Internal OTP (Over Temperature Protection) and OVP (Over Voltage Protection) to prevent the circuit from being damaged due to abnormal conditions.
