The HT7L5600 is primary-side feedback flyback LED driver with output current accuracy of ±3% and power factor values exceeding 0.9. It also possesses the advantages of ambient temperature change insensitivity as well as easy to setup system parameters. The HT7L5600 provides primary-side feedback flyback function which can control LED current values accurately to ensure the system is able to maintain a stable LED output current even under conditions of wide input voltage variations and varying number of LED outputs.
Several protection functions are also included such as Output Short Protection, Cycle by Cycle Current Limit, Output Over Voltage Protection, Over Voltage and Over Temperature protection to ensure safe and reliable operation. The HT7L5600 is suitable for safer and higher efficiency LED lighting control applications.
