LD7513 - Primary Side Quasi-Resonant BJT Controller

Description

The LD7513 is an excellent primary side feedback BJT controller with CV/CC operation, integrated with several functions of protections.

It minimizes the components counts and is available in a tiny SOT-26 package.

Those make it an ideal design for low cost applications.

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 regul.
