LNK454 Power Integrations Datasheet

LNK454 Key Features

• Optimized for non-isolated flyback designs
• Frequency jitter greatly reduces EMI filter size and costs
• Low dissipation direct sensing of LED current
• 725 V integrated MOSFET allows small bulk capacitance and maximizes power capability
• Latching shutdown protection for short-circuit / open feedback and output overvoltage
• Auto-restart for overload condition
• Hysteretic thermal shutdown
• Meets high-voltage creepage between DRAIN and all other pins both on PCB and at package EcoSmart ®
• Energy Efficient
• High power factor optimizes system lumen per watt by reducing input VA
