Together, they form a 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 inverters in LCD-TV applications. The IC is said 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 UBA2072 is designed to operate over a wide low voltage inverter supply, ranging from 9V to 30V, matching the requirements of larger LCD monitors LIPS structures and classical 24Volt supplied LCD-TV backlight inverters. The NXP UBA2072 and UBA2074 LCD backlight inverter controllers are available immediately. High volume pricing ranges from $ 0.65 per piece for the UBA2072 to $ 0.70 per piece for the UBA2074.
