MAX8752 EVALUATION KIT AVAILABLE TFT LCD Step-Up DC-DC Converter General Description The MAX8752 is a high-performance, step-up DC-DC converter that provides a regulated supply voltage for active-matrix thin-film transistor (TFT) liquid-crystal displays (LCDs). The MAX8752 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. The input supply voltage of the MAX8752 is from 1.8V to 5.5V. The MAX8752 operates with a switching frequency of 1.2MHz, allowing the use of ultra-small inductors and lowESR ceramic capacitors. The current-mode architecture provides fast transient response to the pulsed loads typical of LCD source-driver applications.
