“By bringing down the cost of LEDs, leading lighting manufacturers are accelerating their adoption in the residential and commercial lighting markets. The SSL2109 LED controller IC offers a very low electronic bill of materials for high-efficiency LED driver applications, a very low cost of design, and flexibility in optimizing external MOSFET selection across an extremely wide range of power levels, also with cost in mind,” said Ryan Zahn, general manager, lighting solutions product line, NXP Semiconductors.
Key Features
The SSL2109 is a controller-only version of the SSL2108x family of LED driver ICs, with many similar features, including:
A high integration level, with only 15 components required on the PCB
Small PCB area measuring only 18 x 22 mm in reference designs
High efficiency up to 95%
Low electronic bill of materials (eBoM) for LED driver applications
Tight LED current regulation, better than 5%
Direct PWM dimming possible
A complete set of built-in protections, including LED temperature protection via an NTC temperature sensor
Ease of design-in and manufacturing
High reliability, with IC lifetime matching or surpassing LED lifetime
Availability
The SSL2109 controller-only buck LED driver is available immediately. NXP will showcase the SSL2109 at LIGHTFAIR International 2012 in Las Vegas, Nevada from May 9-11 (booth 3335), and at the Guangzhou International Lighting Exhibition from June 9 -12, 2012.
In addition, NXP will release two additional members of the SSL2108x family – the SSL2108xA and SSL2109A – at the end of June. The SSL2108xA and SSL2109A remove the short winding protection feature.
