LNK417EG

LED Driver IC Overview

The LNK417EG is a LinkSwitch-HP family offline switcher integrating a 700 V power MOSFET and controller. It operates from an AC input of 85 VAC to 265 VAC with a nominal frequency of 132 kHz. The device provides precise primary-side regulation (PSR) achieving ±5% CV accuracy without optocouplers. It supports constant voltage outputs up to 90 W and includes programmable current limit, burst mode for light-load efficiency, and comprehensive protection features including OVP, UVP, OTP, and SCP.

LED Driver IC Procurement Notes

Verify the specific suffix 'EG' corresponds to the eSOP-12B package variant when sourcing. Confirm that the component meets the required RoHS compliance standards for your target market. Ensure the ordering quantity matches the manufacturer's standard tube packaging specifications. Cross-reference the date code to verify manufacturing recency if long-term storage is anticipated before assembly.

LED Driver IC Selection Notes

Select this component for designs requiring high power density and reduced bill-of-materials costs by removing secondary feedback loops. The integrated 700 V MOSFET suits applications operating within standard universal input voltage ranges. Consider the thermal performance of the eSOP-12B package for the intended power level. Verify that the fixed 132 kHz switching frequency aligns with your EMI filter design constraints.

LED Driver IC Part Context

This part belongs to the LinkSwitch-HP series, designed for high-performance offline power conversion. The series focuses on minimizing external component count while maintaining strict regulatory compliance for energy efficiency. It targets applications where size reduction and cost optimization are critical design drivers.

LED Driver IC Replacement Considerations

No direct pin-to-pin replacement is publicly confirmed for the LNK417EG. Designers should evaluate alternative LinkSwitch-HP variants or other primary-side regulated controllers, noting that functional compatibility may require schematic modifications.
