Most modern electronic systems rely on multiple internal voltages to operate various functions such as computing, communication and actuation (heat, light, sound, motion etc). Traditional methods of designing multiple outputs force designers to make tradeoffs between efficiency, accurate output regulation, and system performance. The InnoMux-2 IC offers a revolutionary new way to design multi-output PSUs by providing up to three independently regulated voltage outputs or two voltage output and a constant current output from a single stage, achieving a compact and efficient power subsystem with accurate regulation and low component count. This increases efficiency, reduces losses and saves PCB space.
By independently regulating and protecting each output, the InnoMux-2 family eliminates multiple downstream conversion stages. This increases efficiency by up to 10 percent, and reduces BOM count thanks to the elimination of bleed resistors and post regulators.
The InnoMux-2 IC also includes an LED backlight controller that supports multi-mode dimming – making it ideal for monitors, TVs and appliances with lighting or display requirements.
The new IC topology improves multi-output offline power conversion. Systems are 10% more efficient, with 20% more standby power due to the elimination of output bleed circuits. A 50% reduction in parts count is achieved because post regulators are not required. And ±3% output accuracy is achieved across line and load, with each output having the ability to control switching.
Typical applications include TVs, monitors, appliances, networking, home and building automation, LED emergency lighting and industrial power supplies.
