InnoMux2-EP in InSOP-T28D

InnoMux

InnoMux-2 Off-Line Zero Voltage Switching (ZVS) Flyback Switcher IC for Multi-Output Applications

  • InnoMux2-EP - Up to Three CV Outputs or One CV & One CC Output for Dimmable LED String
  • InnoMux2-BL - One CV and up to Four CC Outputs for Dimmable LED Strings in Monitors or Display Panels

Most modern electronic systems rely on multiple internal voltages to operate various functions such as computing, communication and actuation function – typically heat, light, sound or motion of some kind. But losses in each conversion stage are compounded, degrading system performance and generating heat. 

The InnoMux-2 IC overcomes this challenge 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 sub-system with low component count.

The InnoMux-2 family of single-stage, independently regulated multi-output offline power-supply ICs consolidate AC-DC and downstream DC-DC conversion stages into a single chip, providing up to three independently regulated outputs for use in white goods, industrial systems, displays and other applications requiring multiple voltages. 

Elimination of separate DC-DC stages slashes component count, reduces PCB footprint and increases efficiency by as much as 10 percentage points compared to traditional two-stage architectures. Efficiency is aided by the ICs’ 750 V PowiGaN gallium-nitride transistors, zero-voltage switching (without an active clamp) and synchronous rectification.  

Highlights

  • Single-stage power conversion for high efficiency
  • Eliminates post-regulators
      - Up to 10% higher efficiency
      - Low component count
      - Less than 30 mW no-load consumption
  • Up to three independently regulated outputs
      - Constant voltage and constant current outputs
      - Less than ±1% combined load/line/cross regulation
