LNK413EG

LED Driver IC Overview

The LNK413EG is a LinkSwitch-PH family integrated circuit designed for high-performance, non-isolated LED driver applications. It integrates a 700V power MOSFET with a current-mode controller and high-voltage switched current source. The device operates from universal AC line voltages, eliminating the need for an optocoupler. Key electrical parameters include a fixed output current capability of up to 500mA and a maximum switching frequency of 132kHz. It supports dimming control via external components and features comprehensive protection mechanisms including overvoltage lockout, thermal shutdown, and open/short load detection.

LED Driver IC Procurement Notes

Verify the specific suffix (e.g., EG) to confirm package type and lead-free status. Confirm RoHS compliance and REACH status with the manufacturer or authorized distributor before procurement. Ensure the ordering quantity matches standard packaging units. Check for any recent lifecycle notices regarding obsolescence or last-time buy status.

LED Driver IC Selection Notes

Select the LNK413EG for designs requiring high efficiency in non-isolated topologies. Evaluate the required LED string voltage against the device's operating range. Consider thermal management requirements due to integrated MOSFET dissipation. Verify compatibility with desired dimming protocols. Ensure input voltage range matches the target application's supply characteristics.

LED Driver IC Part Context

The LNK413EG belongs to the LinkSwitch-PH family from Power Integrations, specialized for LED lighting. This series focuses on replacing traditional isolated flyback converters with simpler, cost-effective non-isolated solutions. It targets applications where safety isolation is not mandated or can be achieved through other means, prioritizing system reliability and reduced component count.

LED Driver IC Replacement Considerations

No direct pin-to-pin replacement is officially confirmed for the LNK413EG. Designers should evaluate alternative LinkSwitch-PH variants or other non-isolated LED driver ICs from different manufacturers if pin compatibility is critical. Functional equivalence must be verified against electrical specifications.
