Applications Information
PCB Layout
When laying out the PCB for the AL8806 the following should be observed:
Application Example
Typical application example for the AL8806 is the MR16 lamp. They typically operate from 12V
electromagnetic transformers or electronic transformers.
As a replacement in some halogen lamp applications LEDs offer a more energy efficient solution – providing no radiated heat
and no Ultra Violet light.
This application example is intended to fit into the base connector space of an MR16 style LED lamp. The design has been
optimized for part count and thermal performance for a multi-substrate LED in the Lens section.
The AL8806 guarantees high level of performance both with 12V
