The device provides many protection functions and uses ultra low power circuit design, and is optimized to restrict EMI. By integrating a Non-Audible Noise Green Mode Control Structure, users can implement a single circuit for different LED load levels for various series/parallel configurations but still maintain high efficiency for different load conditions. 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), Over-Temperature Protection (OTP) for external thermistor sensing, and a Soft-Start function to reduce inrush currents during LED power system initialization for the prevention of device burn-out. The HT7L2102 provides a 1~99% PWM Dimming Range with duty-cycle scale precision lower...
