LNK460VG

LED Driver IC Overview

The LNK460VG is a LinkSwitch-PL series IC designed for non-isolated LED drivers, specifically targeting 100W A19 incandescent replacements. It operates within a 195–265VAC input range (47–63Hz) to drive an LED string rated at 78V with a constant current of 230mA. The device achieves high efficiency of 93% and high power factor. It integrates the controller and power switch in a compact eSOP-12 package.

LED Driver IC Procurement Notes

Verify component authenticity through authorized Power Integrations distributors or official manufacturer channels. Confirm the specific suffix 'VG' matches the required package and temperature grade specifications. Ensure compliance with relevant RoHS standards and check for any product discontinuance notifications prior to finalizing procurement plans.

LED Driver IC Selection Notes

Select this component for designs requiring high power factor and efficiency in non-isolated topologies. It is suitable for applications needing TRIAC dimmability. Verify that the target LED string voltage aligns with the 78V rating and that the input voltage range matches the local mains supply requirements.

LED Driver IC Part Context

The LNK460VG belongs to the LinkSwitch-PL family from Power Integrations. This series combines a high-voltage switched current source with frequency jittering and control logic. It is engineered to reduce system cost and size by eliminating optocouplers and transformer isolation in specific LED driver architectures.

LED Driver IC Replacement Considerations

Consult official documentation for confirmed substitute part numbers. Verify pin compatibility and electrical specifications before substituting.
