SUNNYVALE, Calif., Feb. 5, 2010 – Alpha & Omega Semiconductor Inc. has expanded its EZBoost family with its first white LED backlight driver, the AOZ1950, designed and optimized for providing backlighting solutions for the latest portable devices using medium-size LCD panels, such as netbooks, media players and navigation devices.

Integrated protection features allow for a more robust system design while reducing overall external component count. The high-performance current-mode boost regulator operates from an input voltage range of 2.7 to 5.5 V, and the integrated and proprietary Trench metal-oxide semiconductor field-effect transistor boost switch allows the device to generate a regulated output voltage as high as 55 V with an input switch current of 750 mA. The high-voltage and low on-resistance boost switch allows the driver to power up to 12 LEDs in series. In addition, the driver integrates several system safety features such as output overvoltage protection, a “true-off” input switch, short-circuit protection and a cycle-by-cycle current limit.

The driver is available in a 10-pin 3 × 3-mm dual flat no-lead package and operates over the -40 to 85 °C ambient temperature range.
