2 Layers PCB 10 x 16.5 mm FR-4, 1 mm, 1, HASL with lead, White Solder Mask, Black silkscreen; WS2813 buffer and repeater for long range serial transmission
This document is an engineering report describing the design of a non-isolated, step-down LED driver (power supply) using the LYTSwitch-4 series device LYT4312E.
DER-359 provides a single 8 W dimmable constant current output.
The main design goal is to achieve high efficiency to increase luminous efficiency and reduce size. This allows the driver to fit into the BR30 lamp and be as close to the production design as possible.
2-layer PCB 38.7 x 49.5 mm FR-4, 1.6 mm, 1, with wire spray tin, red solder mask, white silkscreen; lightning detector.
