Flyback controller for LED luminaire designs
The Infineon ICL8800XUMA1 is an AC DC offline switcher controller built for LED lighting applications, using a flyback topology with integrated dimming support. It operates from an 8 V to 24 V supply rail and is rated over a -40°C to 125°C junction temperature range, suiting it for enclosed luminaire environments where ambient heat builds up.
Package, footprint, and supply integration
Housed in an 8-SOIC package (0.154", 3.90 mm width) with the supplier device package PG-DSO-8-82, the ICL8800XUMA1 is a surface-mount controller that requires an external power switch — it has no internal switch. The single-output design keeps the BOM lean for constant-current LED drivers in downlights, streetlights, and industrial troffers.
