LYTSwitch™-6 LED Driver ICs

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.

Features
  • Highly integrated, compact footprint
  • Up to 94% efficient across load range
  • Incorporates a multi-mode quasi-resonant (QR) / CCM flyback controller, 650 V or 725 V
  • MOSFET, secondary-side control, and synchronous rectification driver
  • Integrated FluxLink, HIPOT-isolated, feedback link
  • Exceptional CV/CC accuracy independent of transformer design or external components
  • Accurate output current sensing
  • Less than 250 mW standby power consumption in typical smart lighting applications, allowing designs that easily meet ENERGY STAR and DOE-6 limits
Applications
  • Isolated off-line LED drivers
  • Smart LED lighting
  • High-voltage flyback post regulators
  • Lighting ballasts
