LD7513K controller equivalent, primary side quasi-resonant bjt controller.
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 powe.
It provides the functions of ultra-low startup current, green-mode power-saving operation and leading-edge blanking of .
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 cos.
