NXP Semiconductors N.V. has introduced a new controller IC, which offers what the company claims is professional-grade performance for solid state LED (SSL) lighting power supplies.

The GreenChip SSL4101T controller IC is the latest addition to NXP's GreenChip SSL family of products. It enables LED lighting for medium- to high-power commercial and professional applications with less than 20 percent total harmonic distortion (THD), a .99 Power Factor (PF) and a 94 percent efficiency rating.

According to Jacques Le Berre, NXP's director of marketing and business development for lighting solutions, the "green" technology for the controller IC entices more consumers to use LED for a wider-range of professional lighting applications, such as high-bay and low-bay lighting for warehouses and street lamps and those which require bright and dependable illumination.

"Today's LED lighting manufacturers are demanding for increased power supply efficiency at lower costs to be used for new LED applications," Le Berre said.

The GreenChip SSL4101T is based on NXP's proprietary high-voltage process and allows direct startup from the rectified 230V and 110VAC mains power supply.

The multichip module also contains both a flyback controller and a controller for PF correction.

The new GreenChip SSL4101T is ideal for LED lighting applications that require a very efficient, low THD, high PF, true universal input voltage and inexpensive power supply ranging between 10 watt and 300 watt.

The GreenChip SSL4101T is priced at US $3.60 apiece and is available now.
