Power Integrations announced its InnoSwitch3-MX isolated switcher IC family has been expanded by adding three PowiGaN devices. Per a company press release, 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.
Is hosts a single-stage power architecture which, according to the company, reduces losses in display applications by 50%, increasing efficiency to 91% in constant-voltage and current LED backlight driver designs.
It features a breakdown voltage of 750V and is resistant to line surges and swells whih are seen in some regions with unstable mains voltages.
The InnoSwitch3-MX flyback switcher ICs meshes the primary switch, primary-side controller, secondary-side synchronous rectification controller, and PI’s FluxLink high-speed communications link. Its chipset partner, InnoMux IC, which measures load requirements, sends its control instructions.
