LNK 417 EG power Integrations - IC LED Driver OFFL DIM 25W eSIP-7C (Lnk417)

LNK417EG Power Integrations IC LED Driver OFFL DIM 25W eSIP-7C

The LNK417EG is an IC LED driver from Power Integrations. It supports offline dimmable applications up to 25W. This integrated circuit provides a power factor greater than 0.9. It supports TRIAC dimming functionality. The single-stage design integrates power factor correction and constant-current control. This eliminates additional switching stages and bulky electrolytic capacitors. Primary side control enables accurate constant current regulation without an optocoupler. The LNK417EG maintains stable performance across a 90-265 VAC input voltage range. This design contributes to reduced component count.
