Single stage driver ICs target general LED lighting

Suitable for Buck, Buck-Boost or Flyback, in non-isolated or isolated topologies, the family includes selectable Low ripple, Eco-Low THD (PF greater than 0.75) or Low THD (PF greater than 0.9) modes. Designed to start up directly from the high-voltage supply by an internal JFET current source, the LED drivers feature accurate LED current and line regulation. Incorporating all required protection features, the family includes compatibility with wall switches with built-in indication light during standby.

Able to detect all known mains dimmer types and translate the dimmer setting to a continuous LED current in multiple ways, the SSL5301T, SSL5306T and SSL5307T ICs have an extremely high dimmer compatibility and are suitable for use with a bleeder. These LED driver ICs are designed and optimised for mains-dimmable (phase cut dimmable) LED driver solutions. The SSL5511T is suited for offline dimmable LED driver solutions with a control input signal for dimming such as remote-controlled luminaires and smart lamps; while the SSL5101T targets non-dimmable LED fixture solutions or higher power isolated LED retrofit solutions.

The SSL5301T, SSL5511T and SSL5101T drive an external switch for easy power scaling up to 50W of lamp power. The SSL5306T and SSL5307T incorporate a 700V/10Ω MOSFET to support compact solutions up to 10W of lamp power. The SSL5306T is designed for Buck topology and the SSL5307T for Buck-Boost Topology.

Ryan Zahn, General Manager, Lighting Solutions Product Line, NXP Semiconductors, comments: “With the introduction of our new single stage driver ICs we are able to offer LED lamp manufacturers even better performance at a lower overall system cost. These solutions provide maximum configuration flexibility and are supported by our high quality and reliable supply chain.”
