Chipset for display power supplies

Power Integrations has released Innomux, a chipset for display power supplies that, with a single-stage power architecture, reduces losses in display applications. Having increased the overall efficiency in constant-voltage and constant-current LED backlight driver stages by 50%, the chip set achieves up to 91% efficiency.


Innomux includes a controller IC and an InnoSwitch™3-MX isolated switcher IC, which combines the primary FET, the primary-side controller, a secondary-side controller for synchronous rectification, and FluxLink™ high-speed communications technology, thus eliminating the need for an optocoupler. 

InnoMux IC

The control information is dispensed by InnoMux IC, which independently measures the load requirements of each output and directs the InnoSwitch3-MX switcher to deliver the right amount of power to each of the outputs, eliminating the load and cross-regulation challenges. Overall power conversion efficiency increases by 10%, removing the need for.

Constant-current and constant-voltage outputs

The technology introduced by Power Integrations supports both accurately regulated constant-current and constant-voltage outputs simultaneously, supplying one to four channels of constant-current and up to two constant-voltage outputs. This flexibility supports the logic, audio and LED requirements typically seen in TV and monitor displays. The IC provides overload protection for each output.
