NXP Announces GreenChip Solution for Non-Dimmable LED Retrofit Lamps
EINDHOVEN, NETHERLANDS and SAN JOSE, CA--(Marketwire - February 24, 2011) - NXP Semiconductors N.V. (
The SSL21081's high integration level, including a 300V internal switching MOSFET, provides a low component count, using only 14 components in a complete application, and reduces the cost of LED lamps for the end user. With the SSL21081, low-cost applications benefit from advanced features such as better than 5% LED current accuracy and a full range of protections, including LED over-temperature protection. Engineering samples of the SSL21081 will become available in mid-2011 at US $1.70 per piece.
Facts/Highlights:
- NXP SSL21081 is a highly efficient, high-voltage LED driver IC
- Designed for compact LED retrofit lamps for the 100V, 110V and 120V markets
- Reference PCB for the SSL21081 is a highly compact 18 mm x 22 mm
- Operates in a buck or buck / boost mode, with all required circuitry in an 8-pin SO package
- Enables power conversion efficiency above 95 percent, depending on the application
- True current source behavior -- better than 5 percent output current accuracy
- Dimming is possible using direct Pulse Width Modulation (PWM)
- Protection features include easy external temperature feedback, as well as under-voltage lockout, leading-edge blanking, over-current protection, brownout protection and more
- Other GreenChip lighting solutions showcased at Strategies in Light 2011 include the NXP SSL2103 controller IC for dimmable LED Lighting
- NXP is the first semiconductor company to have demonstrated that its mains LED drivers match LED lifetimes, through extended lifetime testing
- GreenChip technology lies at the heart of NXP's cost-effective, high-efficiency power management and lighting ICs, based on NXP's EZ-HV process which enables high-voltage silicon-on-insulator (HV-SOI) ICs
Supporting Quote:
- "The NXP SSL21081 was designed with small size, high integration and high efficiency in mind, allowing retrofit lamp manufacturers to reduce application size and cost and introduce LED lighting in small form factor applications," said Jacques le Berre, director of marketing and business development, lighting solutions, NXP Semiconductors. "As incandescent bulbs continue to be replaced with energy-efficient lighting solutions, we are leveraging our GreenChip technology to drive 'eco-engineering' and reduce power consumption for consumers across the globe."
