Power IntegrationsLNK500PN

The Power Integrations LNK500PN LinkSwitch Offline Switcher 700V Through-Hole is a low-power LinkSwitch offline switcher with an integrated 700V power MOSFET for simple universal-input flyback supplies.

Technical description

The LNK500 integrates a high-voltage MOSFET and switching control in one IC, reducing external components in small offline SMPS. The PN version is through-hole and is intended for applications in the few-watt range.

Indicative applications

Small AC/DC adapters, auxiliary supplies, low-power chargers and repair of offline flyback SMPS.

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.
