GENERAL DESCRIPTION
The HT7L2103 is an advanced, highly integrated LED Lighting Driver using an AC-DC isolation topology. The device provides many protection functions and uses ultra low power circuit design, and is optimized to restrict EMI. By integrating a special multi-function interface, this device can be used for different LED power topologies such as Primary Feedback Isolation Flyback, Secondary Feedback Isolation Flyback, DC-DC Buck/Boost/ BuckBoost. This device also integrates various protection functions for LED Lighting requirements such as Cycle-by-Cycle Current Limiting, Short-Circuit Protection (SCP), Over-Voltage Protection (OVP), Internal Over-Temperature Protection (OTP), and a Soft-Start function to reduce inrush currents during LED power system initialization for the prevention of device burn-out. The HT7L2103 provides a 1~99% PWM Dimming Range with duty-cycle scale precision lower than 1%.APPLICATIONS
