Description
LNK403-409EG LinkSwitch®-PH Family
LED Driver IC with TRIAC Dimming, Single-Stage PFC and Primary-Side Constant Current Control
Product Highlights
Dramatically Simplifies Off-line LED Drivers Flicker-free phase-controlled TRIAC dimming Single stage power factor corrected and accurate constant
current (CC) output Eliminates optocoupler and all secondary current control
circuitry Eliminates all control loop compensation circuitry Simple primary-side PWM dimming interface Universal input voltage range Enables designs that are electrolytic-free
Accurate and Consistent Performance Compensates for transformer inductance tolerances Compensates for line input voltage variations Frequency jittering greatly reduces EMI filter size and costs
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
EcoSmart® – Energy Efficient Low standby power remote ON/OFF feature
(<50 mW at 230 VAC) No current sense resistors – maximizes efficiency High efficiency operation, >85% achievable
Green Package Halogen free and ROHS compliant package
Applications Off-line LED driver
