LNK457D/V规格书详情
Description
The LinkSwitch-PL family enables a very small and low cost single-stage power factor corrected constant current driver for
solid state lighting. Optimized for direct LED current sensing, the LinkSwitch-PL operates over a wide input voltage range
delivering an output power of up to 16 W. The LinkSwitch-PL control algorithm provides flicker-free TRIAC dimming with minimal external components.
Product Highlights
Dramatically Simplifies Off-line LED Drivers
• Flicker-free phase-controlled TRIAC dimming
• Single stage power factor correction and accurate constant current (CC) output
• Very low component count with small non-electrolytic bulk capacitor for compact replacement lamp designs
• Compact SO8, eSOP, and eDIP packages
• Completely eliminates control loop compensation
Advanced Performance Features
• Optimized for non-isolated flyback designs
• Frequency jitter greatly reduces EMI filter size and costs
• Low dissipation direct sensing of LED current
Advanced Protection and Safety Features
• Cycle skipping regulation for abnormally low output power to clamp peak output current delivered
• 725 V integrated power MOSFET allows small bulk capacitance and maximizes power capability
• Short-circuit, overload, open feedback and output overvoltage protection
• 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 input VA
• Control algorithm balances switching and conduction losses over line and load to maintain optimum efficiency
