Power IntegrationsLNK305DN

The Power Integrations LNK305DN LinkSwitch-TN Offline Switcher 700V 175mA SO-8C is a LinkSwitch-TN offline power IC with a 700V MOSFET for universal-input supplies up to 175mA MDCM or 280mA CCM.

Technical description

The LNK305DN integrates a power MOSFET and controller for buck, buck-boost and flyback supplies. The DN version is SO-8C SMD.

Indicative applications

Appliance controls, auxiliary supplies and repair of non-isolated AC/DC circuits.

Compatibility note

Selection for repair or a new design must be based on the exact package and pinout, power-supply topology, voltage and current limits, and thermal conditions. Maximum capability depends on the application design.
