Alpha & Omega Semiconductor, Sunnyvale, CA, has expanded its EZBoost™ family with a white LED backlight driver, the AOZ1950. The AOZ1950 provides backlighting solutions for portable devices using medium-sized LCD panels such as netbooks, media players, and navigation devices. The AOZ1950 is a high performance current-mode boost regulator that operates from an input voltage range of 2.7V to 5.5V. Its integrated AOS Trench MOSFET boost switch allows the device to generate a regulated output voltage as high as 55V with an input switch current of 750mA. www.aosmd.com
