MAX8758 Overview
The device is optimized for thin-film transistor (TFT) liquid-crystal display (LCD) applications. The step-up DC-DC regulator provides the regulated supply voltage for the panel source driver ICs. The converter is a high-frequency (640kHz/1.2MHz), current-mode regulator with an integrated 14V n-channel power MOSFET.
