LD7513K Primary Side Quasi-Resonant BJT Controller

The LD7513K is an excellent primary side feedback BJT controller with CV/CC operation, integrating with several functions of protections. It minimizes the components and is available in a tiny SOT-26 package. Those make it an ideal design for low cost applications. It provides the functions of ultra.

LD7513K 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 will accompany with some serious load regulation effects. To deal with this problem
