LCD Monitors

Power Integrations offers a range of products designed for LCD monitor applications. Each IC includes a ≥700 V power MOSFET combined with control and protection circuitry on a single chip. Energy efficient and designed to meet all existing and proposed energy saving standards worldwide, Power Integrations solution can help reduce cost and speed up the introduction of new products.

The InnoMux™ chipset consists of an InnoMux controller IC partnered with an InnoSwitch™3-MX isolated switcher IC. The chipset’s unique single-stage power architecture reduces losses in display applications by increasing overall efficiency in constant-voltage and constant-current LED backlight driver stages by 50% compared to conventional solutions, achieving up to 91% efficiency. Additionally, TV and monitor designers can realize over 50% reduction in component count, reducing manufacturing cost and providing an associated improvement in board reliability.
