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 LED driver
