Descripción
- DN05050/D, 12V/18W Hi-Power Factor Constant Voltage LED Driver. Normally high power factor LED drivers provide a regulated constant current output to drive a string of LEDs. In certain circumstances, the LED load may have a built in constant current LED driver so all that is need to drive the LED load is a power factor corrected constant voltage driver commonly referred to as an LED Power Supply. It is common for these supplies to generate 12V, 24V or even a higher voltage. The focus of this design note is the development of an isolated offline, high power factor corrected single stage constant voltage supply which supports AC mains from 200 - 305 Vac. This addresses AC line voltages found in many parts of the world as well as the 277 Vac commercial input required for the United States
