業界第一顆真正的高壓inverter IC.(NXP2074)

NXP - Industry's first high-voltage full bridge inverter for LCD backlights

Published Nov 29 2007 [Printer friendly version] [Email article to a friend] [More Semiconductor articles]

Availability of its high-voltage, full bridge fluorescent backlight controller IC, the UBA2074, and its low-voltage twin, the UBA2072, has been announced by NXP Semiconductor, the independent semiconductor company founded by Philips.

Together, the device form a new family of full-bridge fluorescent backlight controller ICs, designed specifically to address the trend toward growing display sizes and supporting the increased use of high-supply voltage backlight inverter solutions in LCD-TV applications. In response to customer requests, the company will manufacture DC-AC inverter controller ICs to drive cold-cathode fluorescent lamps, CCFL, or external electrode fluorescent lamps in LCD back lighting applications to support displays of all sizes.

The NXP UBA2074 is believed to be the industry's first, true high-voltage full bridge inverter controller IC, able to directly drive up to 550V supplied full bridges without the need of external level shifters or gate drive transformer constructions. The ability to drive high voltage full-bridge inverter structures, meets the current and near future requirements of higher POWER, high and medium supply voltage full-bridge backlight inverter solutions. The IC supports the continuously increasing LCD TV panel sizes and growing backlight power requirements and enables the creation of highly efficient high-power fluorescent backlight inverter designs on LCD-TV integrated power boards. Meanwhile the UBA2072 is designed to operate over a wide low voltage inverter supply, ranging from 9V up to 30V, matching the requirements of larger LCD monitors LIPS structures and classical 24V supplied LCD-TV backlight inverters.

"With the falling cost of LCD televisions, consumers are choosing increasingly larger LCD TVs, which require greater amounts of backlight power. This drives up the power requirements and cost of the LCD-TV power supply" said Kees Schetters, marketing director, NXP SEMICONDUCTORS. "In addition, the LCD-TV market is extremely competitive, requiring an ever present focus on driving system cost down. One of the areas where large cost savings can be made is within the power management domain of an LCD-TV. This is achieved by moving from traditionally panel integrated 24V inverter solutions to, set-level LCD-TV Integrated Power Supply Boards containing both the LCD-TV power supply as well as a high voltage supplied backlight inverter. This solution serves two goals as it increases the overall power EFFICIENCY of an LCD-TV, and also drives down the total LCD-TV power management cost."

The end application of the UBA2074 is full-bridge high-voltage and medium-voltage LCD-TV fluorescent lamp, CCFL/EEFL, backlight inverters. The UBA2074A, without hard switching protection, is targeted at 60V full-bridge, medium-voltage backlight applications, while the UBA2074, with hard switching protection has its focus on 155V to 400V full-bridge, high-voltage backlight applications. The UBA2072 is very similar to the UBA2074, with the main difference that it has been designed specifically for a low voltage full bridge application limited to 30V, says the company.

這周終于有機會見到并測試了一下NXP的高壓方案.感覺還不錯,主要是板子上面竟然沒有散熱片,就可以做到220W.還有其它兄弟有用過的嗎?分享一下高壓inverter方面的經驗.

板子上面沒有散熱片,就可以做到220W?220W相當于42寸LCDTV的整機功耗,就算你是移相全橋或者LLC,也不可能沒有散熱片啊?

我們公司一直和飛利蒲合作,他們的LCD和高壓INVERTER方案我都了解.
LLC用的是TEA1601 反激用是TEA1533 變壓器共模電感都是自己開的模.
業內已有很多家都開始用他們的變壓器.
