MILPITAS, CA March 20, 2008 Linear Technology announces the LTC3524, an integrated BIAS and white LED power converter solution for small to medium sized (3" to 7") thin film transistor (TFT) liquid crystal display (LCD) panels. The device operates from an input voltage range of 2.5V to 6V, enabling it to accommodate multicell alkaline/NiMH batteries as well as single cell Li-Ion. Each low noise output of the TFT converter is fully adjustable enabling it to power a wide array of LCD panels. The LTC3524 can generate up to 25mA at 6V for the AVDD channel, and up to 2mA at 20V and -20V for the respective VGH and VGL bias requirements with controlled power-up/power-down sequencing. |
