MAX1661 Datasheet (Maxim) - Serial-to-Parallel/Parallel-to-Serial Converters and Load-Switch Controllers

MAX1661, Serial-to-Parallel/Parallel-to-Serial Converters and Load-Switch Controllers

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
