LYT4212L

LYT4212L - 15W Isolated LED Driver IC

The LYT4212L from Power Integrations is a high-performance LED driver IC in the LYTSwitch-4 family, designed for isolated offline LED lighting applications up to 15W. This integrated controller combines a 725V power MOSFET with advanced control circuitry in a compact eSIP-7F package, enabling cost-effective, high-efficiency LED driver designs for commercial and industrial lighting.

Key Features & Benefits

• Multi-Topology Support: Flyback, Buck (Step-Down), and Boost (Step-Up) configurations for design flexibility
• High Integration: Internal 725V switch eliminates external MOSFET, reducing BOM cost and board space
• Wide Operating Range: -40°C to 150°C junction temperature for demanding environments
• High Efficiency: 140kHz switching frequency with 99.9% duty cycle capability optimizes performance
• Isolated Output: Galvanic isolation for safety-critical lighting applications
• Compact Through-Hole Package: 7-lead eSIP with formed leads for easy PCB assembly

Typical Applications

• LED bulbs and retrofit lamps (A19, PAR, MR16)
• Commercial downlights and panel lights
• Industrial and outdoor area lighting
• Emergency and exit lighting systems
• Architectural and decorative lighting
