Step-Up DC-DC Converter for TFT-LCD

Maxim Integrated Products(NASDAQ: MXIM) introduces the MAX8740, a high-performance, step-up DC-DC converterthat provides a regulated supply voltage for active-matrix thin-film transistor (TFT) liquid-crystal displays (LCDs). The MAX8740 incorporates current-mode, fixed-frequency, pulse-width modulation (PWM) circuitry with a built-in n-channel power MOSFET to achieve high efficiency and fast transient response.
