DC/DC steps up to active-matrix LCDs

Sunnyvale, Calif.&#8212Maxim Integrated Products’ MAX8727 provides a regulated 24 volts from a 2.6-5.5 volt input for powering active-matrix, thin-film transistor LCDs (AMLCDs). The current-mode, fixed-frequency PWM boost controller, with built-in n-channel MOSFET, delivers high efficiency (90 percent, nominal), fast loop performance.
