LNK415E集成電路（IC）的LED驅(qū)動(dòng)器規(guī)格書PDF中文資料

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
