LNK418L
Description
The LinkSwitch™-PH dramatically simplifies implementation of LED drivers requiring long lifetime, high efficiency, PF >0.9, and TRIAC dimming capability (LNK403-410). The single-stage combined power factor and constant-current controller eliminates a switching stage and the electrolytic bulk capacitor.
Key Features
- 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
