YugenFlow v2 is a compact, easy-to-use, low-power smart thermal sensor board that uses low-resolution thermal sensors to detect the presence of people and determine whether they are moving in a given direction. The sensor determines the direction along an axis, the physical meaning of which depends on how the sensor is mounted. YugenFlow does not require motion to detect presence, but can use it to determine orientation. The sensor can detect and "track" up to two people simultaneously from a distance of approximately 40 centimeters. It's also very fast.
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.
