Reference Designs

The main purpose of this reference design is to demonstrate a very good compatibility of Power source boost 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 20W: 30-40V LED voltage : 500mA Regulated LED Current : 86% Typical System Efficiency: High Power Factor > 0.9: and output Open-Circuit Protection.
