IMX2065C-H411
Isolated Flyback Switcher IC with One CV and up to Four CC Outputs for Dimmable LED Strings in Computer Monitors or Appliances with Display Panels
Each IMX206x Switcher IC Partners with Up to Two IML204DG Four-Channel LED Backlight Controller ICs
Product Details
The InnoMux2-BL IC provides accurate, isolated, offline CV and CC regulation using a single transformer, dramatically reducing power sub-system component count and board area. The single-stage, multiple output, architecture eliminates DC/DC post regulators, providing regulated outputs.
InnoMux-2 IC-based designs have low BOM count and small size. The family incorporates both primary and secondary side
controllers, with protection, sense elements and a safety-rated feedback mechanism (FluxLink) into a single IC. The InnoMux-2 IC also includes a multi-mode LED backlight controller making it ideal for monitors, TVs and appliances with lighting or display requirements, and partners with the IML204DG to implement up to four CC strings for high-end displays.
InnoMux2-BL contains enhanced features for maximizing conversion efficiency including quasi-resonant switching in DCM operation, accurate SR control and minimum-threshold-regulation for the LED driver.
Product Highlights
