LD7513K - Primary Side Quasi-Resonant BJT Controller

General Description

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.

Key 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, the LD7513K consists of dedicated load regulation compensation circuit to enhance its performance. Features.
  • Primary-Side Feedback Control with Quasi.

LD7513K 03/04/2016 Primary Side Quasi-Resonant BJT Controller with CV/CC Operation REV. 00 General Description 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-low startup current, green-mode power-saving operation and leading-edge blanking of the current sensing. Also, the LD7513K features Internal OTP (Over Temperature Protection) and OVP (Over Voltage Protection) to prevent the circuit from being damaged due to abnormal conditions.
