LD7513

For KCToEnCdifOenlntyial Preliminary Datasheet LD7513 Primary Side Quasi-Resonant BJT Controller with CV/CC Operation REV: P00 The values contained in this preliminary datasheet are for reference only. Users should verify for a current and complete document before placing orders. General 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. It provides functions of ultra-low startup current, green-mode power-saving operation and leading-edge blanking of the current sensing. Also, the LD7513 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...
