DI-173, TNY279GN, 14W, LED Driver Power Supply With High Efficiency
Conception de référence par: Power Integrations
DI-173, Reference Design for TNY279GN, 20V, 14W constant voltage and constant current output power supply. The light output from an LED array is proportional to the current flowing through it. As such, LED drivers should have a constant current as opposed to a constant voltage output
