Power IntegrationsLNK304PN

The Power Integrations LNK304PN LinkSwitch-TN Offline Switcher 700V 120mA DIP-8B is a LinkSwitch-TN offline switcher with a 700V MOSFET for compact universal-input power supplies in through-hole DIP-8B.

Technical description

The LNK304PN supports low-power buck, buck-boost and flyback topologies. At 230VAC it is specified for up to 120mA MDCM or 170mA CCM.

Indicative applications

Appliance supplies, auxiliary power rails, relay/triac controls and LinkSwitch-TN repairs.

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.
