New flexible digital LED driver IC platform from NXP

NXP Semiconductors has unveiled a new family of single stage driver ICs for compact, high-efficient, high-performance and cost-effective general LED lighting solutions complementing NXP’s broad range of GreenChip SSL products. The new platform includes the SSL5301T, SSL5306T, SSL5307T, SSL5511T and SSL5101T LED driver solutions from 4 Watt up to 50 Watt of lamp power.

All products have been designed in the compact and economical SO-8 package.

The product family is applicable for Buck, Buck-Boost or Flyback, in non-isolated or isolated topologies and includes three selectable modes: Low ripple, Eco-Low THD (PF>0.75) or Low THD (PF>0.9). Other benefits include: accurate LED current and line regulation and compatibility with wall switches with built-in indication light during standby. The LED driver ICs have also been designed to start up directly from the high-voltage (HV) supply by an internal JFET current source and incorporate all required protection features.

The SSL5301T, SSL5306T, SSL5307T single stage LED driver ICs are designed and optimised for mains-dimmable (phase cut dimmable) LED driver solutions. The SSL5301/06/07T can detect all known mains dimmer types and translate the dimmer setting to a continuous LED current in multiple ways. This means that they have an extremely high dimmer compatibility and are suitable for use with a bleeder. 

The SSL5301T, SSL5511 and SSL5101, drive an external switch for power scaling up to 50Watt of lamp power. The SSL5306T and SSL5307T have an incorporated MOSFET of 700V/10Ohm to support compact solutions up to 10Watt of lamp power. The SSL5306T is designed for Buck topology and the SSL5307T Buck-Boost Topology and will be released for mass production in Q3 2014.

The SSL5511T is a compact single stage LED driver IC for offline dimmable LED driver solutions with a control input signal for dimming such as remote-controlled luminaires and smart lamps. The SSL5101T targets non-dimmable LED fixture solutions or higher power isolated LED retrofit solutions. With the introduction of the platform, NXP also adds fourteen new reference boards to the NXP LED Driver Solutions Selection Guide. NXP’s cost-effective LED Driver Solutions simplify lamp design with the right form factor to streamline the design-in process, and extend lifetime and reliability.
