LNK302G-TL

AC DC Converters, Offline Switchers Overview

The LNK302G-TL is an AC/DC converter from the LinkSwitch-TN family, designed for high-voltage offline switcher applications. It integrates a 700 V power MOSFET with a current-mode controller and high-voltage startup circuit into a single package. The device operates within an input voltage range of 85 VAC to 265 VAC. It supports output currents of 63 mA in minimum discontinuous conduction mode (MDCM) and 80 mA in continuous conduction mode (CCM). Key electrical parameters include a maximum duty cycle of 72% and a typical operating supply current of 68 µA. The component functions reliably across a temperature range of -40 °C to +150 °C.

AC DC Converters, Offline Switchers Procurement Notes

Verify the specific suffix 'TL' indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to procurement. Ensure the part number matches the exact pinout and thermal requirements of the target design.

AC DC Converters, Offline Switchers Selection Notes

Select this component for designs requiring low standby power consumption and minimal external component count. The integrated high-voltage startup reduces bill-of-materials costs. Verify that the required output current falls within the 63 mA MDCM or 80 mA CCM limits defined by the application's transformer design.

AC DC Converters, Offline Switchers Part Context

This part belongs to the LinkSwitch-TN family, which targets ultra-low cost, high-volume applications. It replaces discrete solutions by combining control logic and power switching. The LNK302 variant specifically offers lower output current capabilities compared to higher-power members of the same series.

AC DC Converters, Offline Switchers Replacement Considerations

Check for direct cross-reference availability from Power Integrations. Verify pin compatibility if substituting with other LinkSwitch-TN variants.
