LD7515L

LD7515L 8/5/2015 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 component 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. In most cases, the power supply with primary-side feedback controller would accompany with some serious load regulation effect. To deal with this problem, the LD7515L consists of dedicated load regulation compensation circuit to enhance its performance. Features  Primary-Side Feedback Control with Quasi-...
