ON Semiconductor Introduces its Fourth GreenPoint(TM) Power Supply Reference Design -- Again Delivering Profound Energy Efficiency.

DALLAS -- New 220 watt LCD-TV power supply solution delivers standby power of less than 1 watt

ON Semiconductor (Nasdaq: ONNN), a leading global supplier of power management solutions, today unveiled its fourth GreenPoint(TM) reference design -- this one for 220 watt (W) LCD-TV power supplies. Like the CRT-TV open reference design the company introduced earlier in the month, this flat-screen television design delivers standby power of less than 1 W, addresses all functional blocks of the power supply and meets international regulations for low standby power dissipation.

"The LCD-TV, CRT-TV, ATX and notebook adapter power supply reference designs that ON Semiconductor has successfully developed, built and fully tested during the past year, demonstrate our ongoing dedication to deliver industry-leading, energy efficient power sources," said Andy Williams, vice president of ON Semiconductor's Power Conversion Products Division. "These open reference designs help electronics manufacturers tighten their design cycles and deliver competitive consumer products with reduced energy waste.

"While developing our GreenPoint(TM) power solutions," said Williams, "we work closely with our worldwide customers to assure the creation of effective solutions that directly address present and future power needs. ON Semiconductor plans to continue to deliver 'green' solutions that ease the design burden on our customers for increasingly efficient power supplies."

The Reference Design

To achieve breakthrough performance, the new LCD-TV GreenPoint(TM) reference design utilizes several of ON Semiconductor's advanced power management devices and draws from the company's industry-leading discrete component portfolio.

The enabling devices for the LCD-TV reference design are the newly introduced NCP1395 and NCP5181.

--NCP1395 - a high performance resonant mode controller that offers everything needed to build a reliable and rugged power supply. Its unique architecture includes a 1.0 megahertz (MHz) Voltage Controller Oscillator and protections featuring various reaction times that contribute to a safer converter design, without engendering additional circuitry complexity. This device is offered in an SOIC-16 package, priced at $1.38 per unit in 2,500 unit quantities, and a PDIP-16 package, priced at $1.50 per unit in 500 unit quantities.

--NCP5181 - a high voltage power MOSFET driver that provides two outputs to drive two N-channel MOSFETs. The NCP5181 uses the "bootstrap" technique to ensure proper drive of the high-side power switch. This device is offered in an SOIC-8 package, priced at $1.60 per unit in 2,500 unit quantities, and a PDIP-8 package, priced at $1.74 per unit in 1,000 unit quantities.

Other key devices include:

--NCP1653 - a compact Power Factor Correction (PFC) controller that is ideal for continuous conduction mode (CCM) PFC applications like those found in flat-screens televisions. This device makes the choice of incorporating a PFC front-end into a power supply design easy by reducing part count and providing a robust, cost-effective front-end without range switches. This device is offered in an SOIC-8 package, priced at $0.80 per unit in 2,500 unit quantities, and a PDIP-8 package, priced at $0.88 per unit in 1,000 unit quantities.

--NCP1027 - a highly integrated Switch Mode Power Supply (SMPS) switcher. This device provides improved efficiency at light loads by entering a skip cycle when power demand is low. This device is offered in a PDIP-8 package, priced at $0.95 per unit in 1,000 unit quantities.

Supporting devices include:

--TL431 - a programmable precision reference.

--MBR10H100CT - 100 V, 10 A, H-series SWITCHMODE(TM) power rectifier.

--MBRS260 - 60 V, 2 A, schottky power rectifier.

--MMSZ7V5E - 225 W, 7.5 V, energy rated zener.

A complete documentation package for the LCD-TV power supply is available -- including description, schematic, bill-of-materials, Gerber images and evaluation results. These materials are available at www.onsemi.com, as are the product specifications and other supporting information.
