Beschreibung

This is an engineering report for a linear LED driver demonstration board operated in combination with an Infineon XDPL8218 PFC/Flyback controller.The board is operable up to 60 V input voltage. In the standard configuration the target current is 500 mA. The PFC/Flyback represents the primary side of the LED power supply while the BCR601 system of the demonstration board represents the secondary side. Both sides are separated by galvanic decoupling. To the primary side an OPTO closed-loop feedback control signal is provided. This document contains the technical specification for the LED driver, a description of the main features and circuit and layout descriptions, as well as the measurement results.
