Post to del.icio.us> A commitment to the development of consumer, industrial and communications markets of the new power analog semiconductor solutions for enterprise - analogictech today announced aat282x active matrix thin film transistor (tft) liquid crystal display (lcd) dc / dc converter products group, including a wled drive and vcom buffer, backlit displays for portable power source to provide a fully integrated solution the application of the program's main objectives include car show, digital photo frame, Internet, e-books and handheld gps navigation devices. " will be integrated into portable consumer products in the display need to meet some of the unique and difficult conditions, must have a longer battery life, better energy efficiency and more stringent energy management, "analogic tech, technical marketing manager ray chan said, "Our product is designed in accordance with the requirements of these countries can focus on from 5 inches to 10 inches of different size backlight-type active matrix tft lcd screen offers a variety of flexible and efficient solution for portable device manufacturers to bring significant competitive advantage. "aat282x are analogictech development of integrated power solutions product group panel, a department, the product is to use the built-in negative charge pump with low power consumption to achieve higher efficiency, lower volatility and more strict modulation of the final output 30v, said vgh and vgl voltage. aat282x boost converter operating voltage down to 2.5v, the layout is a variety of portable backlit display devices the ideal choice. aat2822's flagship device, including one for the row and column array gate drive power supply triple-output dc-dc converter, a 28v of drive and a backlit wled for distribution across the screen reference voltage vcom buffer medium according to the requirements of different shows, aat282x product group provide for related functions can be held exceptionally solution, such as removing vcom buffer and backlight options, providing design flexibility to meet any particular display all the unique features of the design required. To minimize the circuit board space, aat282x all product groups are the product of a compact 4mm x 4mm lead-free tqfn package. embedded optional evaluation board, the entire solution can fit in a 30mm x 21mm of the pad. aat282x major unique where lcd bias powero 2.5v to 5.5v input supply rangeo 1.3mhz fixed frequency current-modeo step-up regulatoro fast transient responseo adjustable voltage up to 14.5v (± 1% typical accuracy) o small external inductor and capacitorso integrated soft start and sequencing of all railso short-circuit, over-voltage, and over-tperature protection · charge pump outputs: vgh & vglo up to 13.2v input supply (vdd) o adjustable voltage up to ± 30v @ 20ma (± 3 % typical accuracy) · wled drivero input voltage range: 2.5v to 25vo maximum continuous output: 12v @ 260ma & 28v @ 50mao panel sizes from 5 "to 10" o constant led current with 6% accuracyo pwm dimming control up to 1khz with a high frequency filtered pwmo 1.3mhz switching fixed frequencyo up to 90% efficiency · vcom buffero high-performance § 13v/μs slew rate § 12mhz,-3db bandwidtho ± 75ma output short-circuit currento low 1.5ma quiescent current>
