Power Integrations announced that its InnoSwitch™3-MX isolated switcher IC family has been expanded with the addition of three new PowiGaN™ devices. As part of a chipset with Power Integrations’ InnoMux™ controller IC, the new switcher ICs now support display and appliance power supply applications with a continuous output power of up to 75 W without a heatsink.

The InnoMux chipset employs a unique single-stage power architecture that reduces losses in display applications by 50% when compared to conventional designs, increasing overall efficiency to 91% in constant-voltage and constant-current LED backlight driver designs. Additionally, by eliminating the need for post regulation (i.e. buck and boost) stages, TV and monitor designers can halve component count, improving reliability and reducing manufacturing cost. With a high breakdown voltage of 750 V, the PowiGaN InnoSwitch3-MX parts are also extremely robust and highly-resistant to the line surges and swells commonly-seen in regions with unstable mains voltages (more info, photo: Business Wire).
