NXP SSL5101T

Description

The SSL5101T is an offline controller IC, intended to drive LEDs in general lighting applications.The main benefits of this IC include:• Selectable modes for high power factor or low ripple, allowing a wide LED power range• Single stage topology for small PCB footprint• Ease of design-in• Integrated start-up JFET• Low electronic Bill Of Material (BOM)• Various converter topologies supportedThe 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 all required protection features.
