Datasheet Summary
Powered by GS/AI

The FL7733AMX is a highly integrated PWM controller designed for low-to-mid power LED lighting applications, featuring advanced Primary-Side Regulation (PSR) technology. This product utilizes TRUECURRENT® technology to achieve a constant current output with a tolerance of less than ±1% across a wide range of line voltages, ensuring precise LED brightness control. The device operates within an input voltage range of 80 VAC to 308 VAC and boasts a high power factor greater than 0.9, along with a low total harmonic distortion (THD) of less than 10%. It supports fast startup times of under 200 ms at 85 VAC, thanks to its internal high-voltage startup circuit and adaptive feedback loop control, which minimizes overshoot and undershoot during startup. The FL7733AMX includes multiple protection features for enhanced reliability, such as LED short/open protection, output diode short protection, and over-temperature protection. It is packaged in an 8-pin Small-Outline Package (SOP), making it suitable for compact designs. This LED driver is compatible with analog dimming functions and is ideal for applications requiring a constant current output in the range of 5 W to over 60 W.
