Power Integrations InnoMux and InnoSwitch3-MX GaN increases the output power of high-efficiency display power supply units (PSUs) to 75W. The InnoMux chipset uses a unique single-stage power architecture that reduces losses in display applications by 50%. Power Integrations InnoMux devices also increase overall efficiency to 91% and higher output in constant-voltage (CV) and constant-current (CC) LED backlight driver designs. By eliminating the need for post-regulation (buck and boost) stages, TV and monitor designers can halve component count while improving reliability and cost-effectiveness. With a high breakdown voltage of 750V, PowiGaN InnoSwitch3-MX is also extremely robust. The devices are highly resistant to the line surges and swells commonly seen in regions with unstable mains voltages.
