LED controller IC
The SSL5101T is an offline non-dimmable controller IC, intended to drive non-dimmable LEDs in general lighting applications, like remote-controlled luminaires and smart lamps.
The IC drives an external switch for easy power scaling. It has been designed to start up directly from the High-Voltage (HV) supply by an internal high-voltage current source. Flyback, buck and buck-boost circuit topologies are supported. Primary side sensing provides accurate output current control.
The IC can operate in three switching modes at two switching frequency ranges. It offers tradeoffs between the output current ripple, the mains current Total Harmonic Distortion (THD) and the application size. The IC incorporates many protection features.
