LNK 362 PN power Integrations - AC/DC Converters 2.6W 85-265VAC 2.8W 230VAC OCP 8DIP-7 (LNK362PN)

LNK362PN Power Integrations AC/DC Converter – Energy-Efficient Off-Line Switcher IC

The LNK362PN from Power Integrations is a highly energy-efficient AC/DC converter, part of the LinkSwitch-TN family. This off-line switcher IC is engineered to replace traditional linear and capacitor-fed non-isolated power supplies. It delivers superior performance and energy efficiency at an equivalent system cost, especially for outputs under 360mA. The device integrates a robust 700V power MOSFET, an oscillator, and a simple on/off control scheme. Key features include a high-voltage switched current source, frequency jittering, and cycle-by-cycle current limiting. Built-in thermal shutdown circuitry ensures reliable operation. Start-up and operating power are derived directly from the DRAIN pin, simplifying design by eliminating external bias supplies. An integrated auto-restart circuit safely limits output power during fault conditions like short-circuits or open loops, reducing overall system protection costs. This makes the LNK362PN an ideal solution for compact and reliable power conversion.
