AC DC Converters, Offline Switchers Procurement Notes

Verify the specific suffix 'TL' indicates tape and reel packaging when sourcing. Confirm the manufacturer is Power Integrations to ensure authenticity. Check RoHS compliance status against current regulatory requirements. Validate the SO-8C package dimensions for PCB footprint compatibility. Ensure the part number matches the exact electrical specifications required for the design.

AC DC Converters, Offline Switchers Selection Notes

Select this component for designs requiring integrated flyback converter functionality without external controllers. The 100 kHz frequency allows for compact transformer sizing compared to lower frequency alternatives. Consider the thermal performance limits when designing for high ambient temperatures. The integrated startup circuit simplifies bill of materials by reducing external component count.

AC DC Converters, Offline Switchers Part Context

This part belongs to the LinkSwitch-CV series, which offers enhanced performance over previous generations. It serves as a surface-mount alternative to through-hole DIP packages like the LNK626PG. The DG-TL designation specifically denotes the SOIC-8C package with tape and reel delivery format.

AC DC Converters, Offline Switchers Replacement Considerations

The LNK626PG is a verified through-hole replacement option within the same family. Both parts share identical electrical characteristics and pinout configurations. Designers must account for package differences when selecting between surface mount and through-hole variants.
