Power Integrations' 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. The devices incorporate both primary and secondary controllers, with sense elements and a safety-rated feedback mechanism into a single IC and an innovative the integrated communication link, FluxLink. The family provides accurate controls of both output current and voltage providing a solution that can drive both LED strings for conventional lighting and post regulators for smart lighting from a single design.
