The FL7733AMX from On Semiconductor is a highly-integrated PWM controller utilizing advanced Primary-Side Regulation (PSR) to minimize component count in low-to-mid-power LED lighting applications. It employs TRUECURRENT® technology, ensuring a constant current output with a tolerance of less than ±1% over the universal line voltage range. This driver achieves high power factor (>0.9) and low total harmonic distortion (<10%) across the universal line input range.
Key features include a fast startup time of less than 200 ms at 85 VAC, enabled by an internal high-voltage startup circuit. The adaptive feedback loop control prevents overshoot or undershoot of LED current during startup. The FL7733AMX also incorporates robust system protections such as LED short/open, output diode short, sensing resistor short/open, and over-temperature protection, all operating in auto-restart mode.
Designed for applications requiring analog dimming, this LED driver is suitable for power outputs from 5 W to greater than 60 W. It operates within a wide input voltage range of 80 VAC to 308 VAC. The controller is housed in an 8-pin Small Outline Package (SOP), suitable for surface mount applications.
