Power Integrations LYT6068C
The LYTSwitch™-6 series family of ICs dramatically simplifies the development and manufacturing of off-line LED drivers, particularly those in compact enclosures or with high efficiency requirements. The LYTSwitch-6 architecture is revolutionary in that the devices incorporate both primary and secondary controllers, with sense elements and a safety-rated feedback mechanism into a single IC.FEATURES
