NXP Announces GreenChip for LED Lamps up to 10W
NXP Semiconductors N.V. announced the SSL2115x series of high-efficiency GreenChip™ driver ICs for low-cost LED retrofit lamps. The new SSL21151 and SSL21153 are designed for non-dimmable 5 and 10W LED lamps respectively, providing good current control in flyback and buck-boost configurations. The SSL2115x enables small form-factor LED drivers, using primary-side sensing to regulate current, and offering integrated LED open/short protections, an internal 700V MOSFET, and a circuit enabling start-up directly from the rectified mains voltage. With the use of an additional valley fill circuit, the SSL2115x series can offer a power factor of approximately 0.9.
"To make LED lamps a viable replacement for incandescent light bulbs on a large scale, many manufacturers are exploring ways to bring the average selling price below the $10 mark. At the same time, the luminous efficacy of LEDs is improving steadily, requiring less power to emit more lumens," said Ryan Zahn, general manager, lighting solutions product line, NXP Semiconductors. "By offering a compact, low-cost solution for driving LED lamps up to 10W, we are broadening our portfolio of options for lighting manufacturers focused on delivering both energy savings and value to a broad customer base worldwide."
The new SSL2115x series driver ICs are designed for ultra-low-cost, non-dimmable LEDs using isolated flyback and non-isolated buck-boost topologies, powering up to 5W (SSL21151) and 10W (SSL21153), with a small PCB footprint. Key features include:
Related: Integrated High-Voltage Regulator Transistors from Diodes
-- Low output ripple ?1%
-- Power factor (PF): 0.6 or ~0.9 using valley fill
Opinion: Maximising Synergies between Power Electronics and ICT for improving Energy Efficiency
-- Internal protections, including over-temperature protection (OTP), LED short protection, LED open protection, and undervoltage lockout protection (UVLO)
-- Integrated 700V MOSFET
-- Primary-side sensing without an optocoupler
-- Low component count, with a complete application requiring only 25 components and fitting in GU10 casing
-- Compatibility with IEC 61000-3-2 Harmonics Standards
-- EMC compliance: Class B CISPR22 and FCC Part 15
-- Compact SO7 package
Qualification samples of the GreenChip SSL21151 and SSL21153 driver ICs for high-performance non-dimmable LED applications are now available for ordering, with volume production scheduled to begin in July 2012.

Energy Efficiency with Class D Amplifier Modules
Class-D switching amplifiers are helping audio designers create personal multimedia devices and home audio/visual systems that demonstrate how compact and stylish equipment can also deliver high sound quality and high audio output power. The key to this breakthrough, providing freedom from the large and bulky boxes housing traditional audio products, lies in the class-D amplifier’s high energy efficiency, which is typically around 90%. This allows designers to reduce or eliminate heatsinks as well as using smaller-sized PCBs and smaller components such as transformers, connectors and power supplies.

The Role of Hall Effect Sensors in Power Distribution Infrastructure
Power distribution units (PDUs) form an essential part of modern computing and data communications hardware. They provide multiple outputs for transferring electrical power with maximum efficiency, controlling the power capacity and safeguarding against the possible causes of supply interruption. With an ever increasing need from tech savvy consumers for higher data throughput and greater quantities of data storage capacity, as well as tough international legislation now governing CO&sub2; emissions, the demands being placed on these units are proving challenging for engineering teams to satisfy.
