Power IntegrationsLNK304GN

The Power Integrations LNK304GN LinkSwitch-TN Offline Switcher 700V 120mA SMD-8B is an energy-efficient LinkSwitch-TN offline switcher with a 700V MOSFET for universal-input non-isolated supplies up to 120mA in MDCM.

Technical description

The LNK304 supports low-power buck, buck-boost and flyback topologies. The GN version is SMD-8B and at 230VAC the datasheet specifies up to 120mA MDCM or 170mA CCM.

Indicative applications

Non-isolated AC/DC supplies, appliances, auxiliary rails, relay/LED controls and LinkSwitch-TN service.

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.
