The FL103M is a LED lighting controller produced by Fairchild Semiconductor. It supports an input voltage range of 85-265VAC and a maximum output power of 8.4W. The output voltage is 24V (0.35A). The device has constant-voltage (CV) and constant-current (CC) control without secondary feedback circuitry. It achieves low EMI through frequency hopping. It consumes low power in standby mode and has over-voltage protection, under-voltage protection, over-current protection, and over-temperature protection.
The document presents a Fairchild reference design supporting the inclusion of the FL103M in LED illumination designs. It operates with an input voltage range of 85-265Vac and delivers a rated output of 8.4W at 24V (0.35A). Key features include Constant-Voltage and Constant-Current control without secondary-feedback circuitry, low EMI through frequency hopping, and various protection functions such as UVLO, Over-Voltage, Over-Current, and Over-Temperature.
