AC Line Powered LED Lamps

Enabling leading edge solutions in AC line powered LED lighting applications, Active-Semi leverages over 8 years of high voltage power conversion expertise.

Active-Semi's universal ActivePSR™ and high power quasi-resonant secondary side regulators are an ideal fit for LED lighting systems that demand flyback or buck architectures. Examples of these isolated AC lamp application circuits are shown below, illustrating an ACT365 ActivePSR™ based design providing up to 12.5Watts and an ACT512 ActiveQR™ based design providing up to 60 Watts. Given state-of-the art LED technology at about 100 lumens per Watt, these AC line powered lamp applications provide 1250 lumens and 6000 lumens, respectively.
