SSL5301T Mains dimmable controller for LED lighting Rev. 2 — 30 June 2014 Product data sheet 1. General description The SSL5301T is a mains dimmable controller IC, intended to drive dimmable LEDs in general lighting applications. The main benefits of this IC include: • High dimmer compatibility • Selectable modes for high power factor or low ripple, allowing a wide LED power range • • • • • • • Large dimming range Single stage topology for small PCB footprint Ease of design-in Integrated start-up JFET Low electronic Bill Of Material (BOM) Supports multi-lamp applications Various converter topologies supported 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 detect all known mains dimmer types and translate the dimmer setting to a continuous LED current in multiple ways. It 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 all required protection features. 2.
