On June 5, 2010, Analogic Solutions Solutions Inc. AnalogicTech announced the AAT282X active matrix thin-film transistor (TFT) liquid crystal display (LCD) DC/DC converter product line, including a WLED driver and VCOM buffer for portable backlighting. The display provides a fully integrated power solution. The main application goals of the program include car display, digital photo frame, netbook, e-book and handheld GPS navigation device.
“Integrating portable displays into consumer products requires some unique and difficult conditions that require long battery life, better energy efficiency and tighter energy management,†said Ray Chan, technical marketing manager at Analogic Tech. “Our products are designed to meet these requirements and offer a variety of flexible and efficient solutions for backlit active matrix TFT LCD screens from 5†to 10â€, providing significant competition for portable device manufacturers. Advantage."
The AAT282X is part of AnalogicTech's portfolio of integrated panel power solutions that utilize built-in low-power positive and negative charge pumps for higher efficiency, lower volatility and tighter modulation, resulting in a 30V symmetry output. VGH and VGL voltages. The AAT282X boost converter operates at voltages as low as 2.5V and is ideal for a variety of portable backlit displays.
The AAT2822's flagship device includes a three-output DC-DC converter for powering row and column array gate drivers, a 28V WLED backlight driver, and a VCOM buffer for distributing a medium reference voltage across the display. Depending on the display requirements, the AAT282X product group offers additional solutions for related functions, such as removing VCOM buffers and backlighting options, providing design flexibility to meet all the unique features required for any particular display design.
To minimize board space, all products in the AAT282X product group are available in a compact 4mm x 4mm lead-free TQFN package. When the optional evaluation board is embedded, the entire solution can be placed in a 30mm x 21mm pad.
