LNK306PN Description

To replace all linear and capacitor-fed (cap dropper) non-isolated power supply in the sub 360 mA output current range at equal system cost while providing significantly greater performance and energy efficiency, LinkSwitchTM-TN was created.

A 700 V power MOSFET, an oscillator, a basic On/Off control scheme, a high-voltage switched current source, frequency jittering, a cycle-by-cycle current limit, and thermal shutdown circuitry are all integrated into LinkSwitch-TN devices, which are monolithic integrated circuits. For buck or flyback converters, the start-up and running power are directly obtained from the voltage on the DRAIN pin, doing away with the requirement for a bias supply and related circuitry. The LNK304-306's completely integrated auto-restart circuit safely restricts output power under fault circumstances like short-circuit or open loop, which lowers the cost of system-level load protection and the number of components required.
