The DER-297 reference design uses the LinkSwitch-PL IC in PFC drivers for LEDs. The design describes a driver for B10, GU10, E17, and A19 LED light bulbs, such as Cree’s new XLamp XT-E and XM-L LEDs.

According to Power Integrations, the design reaches 87% efficiency at 115Vac for a 4.3W led driver (86% for 2.9W output) while achieving a power factor greater than 0.9, meeting EN61000-3-2 Class C ...
