Description
This product is not recommended for new designs.
LNK403-410/413-420 LinkSwitch-PH LED Driver IC Family
Single-Stage PFC, Primary-Side Constant Current Control and TRIAC Dimming/Non-Dimming Options
Product Highlights
Dramatically Simplifies Off-line LED Drivers Single-stage combination of power factor correction and
accurate constant-current (CC) output Enables very long lifetime designs (no electrolytic capacitors) Eliminates optocoupler and all secondary current control
circuitry Eliminates control loop compensation circuitry Simple primary-side PWM dimming interface Universal input voltage range LNK403-410 optimized for flicker-free TRIAC dimming
EcoSmart™ – Energy Efficient Single-stage PFC combined with output CC control
Greatly increases efficiency, >90% achievable Reduces component count No current sense resistors Low standby power remote ON/OFF feature (<50 mW at 230 VAC)
Accurate and Consistent Performance Compensates for transformer inductance variations Compensates for line input voltage variation Frequency jittering greatly reduces EMI filter size and cost
Advanced Protection and Safety Features Auto-restart for short-circuit protection Open circuit fault detection mode Automatic thermal shutdown restart with hysteresis Meets high voltage creepage requirement between DRAIN and
all other signal pins both on PCB and at package
Green Package Halogen free and ROHS compliant package
Applications Off-line LE...
