Active-Matrix Liquid Crystal Display (AMLCD) Supply
________________General Description
The MAX1664 integrates power-supply and backplane drive circuitry for active-matrix thin-film-transistor (TFT) liquid crystal displays.
Included are a single-output, pulsewidth-modulation boost converter (0.
25 Ω switch), a dual-output (positive and negative) gate-driver supply using one inductor, an LCD backplane driver, and a simple phase-locked loop to synchronize all three outputs.
High switching frequency (1MHz nominal) and phaselocked operation allow the use of small, minimumheight external components while maintaining low output noise.
