Description

The main purpose of this reference design is to demonstrate a very good compatibility of Power source SEPIC topology LED driver based on TPS92560. This LED driver is designed for converting a power source DC: AC & E-transformer to a regulated LED current. The operating conditions and performance of the reference design are as follows: 12VDC: or 12Vac / 50Hz 60Hz: or 12VAC E-transformer: Output Power 3 ~ 4W: 10 ~13V LED voltage : 300mA Regulated LED Current : 75% Typical System Efficiency: High Power Factor > 0.9: Output Short-Circuit and output Open-Circuit Protection.
