About the solution

Efficient isolated conversion with controlled stress and precise LED regulation

The solution combines an AC input and rectified high-voltage bus, an isolated flyback or resonant primary stage, a dedicated clamping network, efficient secondary rectification and digital control. This architecture supports stable constant-current or constant-voltage output, smooth dimming, low ripple, predictable startup and coordinated protection across wide line and load conditions.

Designed for indoor, outdoor, industrial, commercial and connected lighting

The architecture can be scaled for downlights, panel lights, linear fixtures, high-bay lighting, street lights, horticultural systems, signage and smart luminaires. Digital supervision and telemetry enable configurable dimming curves, energy reporting, thermal derating, fault diagnostics and integration with building or wireless lighting networks.

Power devices and control functions aligned with the critical LED driver stages

High-voltage primary MOSFETs, gate drivers, clamp and snubber devices, fast and Schottky rectifiers, current-sense amplifiers, digital controllers, isolation devices and communication interfaces form a practical semiconductor platform for compact, efficient and reliable LED power-supply designs.
