LYT4218L

LYT4218L - High-Performance 78W LED Driver IC

The LYT4218L from Power Integrations is a highly integrated LED driver IC from the LYTSwitch-4 family, designed for high-efficiency offline LED lighting applications up to 78W. This advanced controller combines a 725V power MOSFET with sophisticated control circuitry in a compact eSIP-7F package, enabling cost-effective, reliable LED driver designs for commercial and industrial lighting.

Key Features & Benefits

• High Integration: Internal 725V MOSFET eliminates external switching components
• Multi-Topology Support: Flyback, buck (step-down), and boost (step-up) configurations
• Wide Power Range: Optimized for LED drivers up to 78W output
• High Efficiency: 140kHz switching frequency with 99.9% duty cycle capability
• Extended Temperature Range: -40°C to 150°C junction temperature for demanding environments
• Simplified Design: Reduces component count and board space vs. discrete solutions

Typical Applications

• Commercial LED lighting (downlights, panel lights, high-bay fixtures)
• Industrial LED drivers and retrofit lamps
• Outdoor and street lighting systems
• Architectural and decorative LED lighting
