PART NUMBER: LNK304PN

Description

The LNK304 electronic module is a custom power supply module produced by LinkSwitch-TN to displace all capacitor-fed (cap dropper) and linear non-isolated power supplies in the under 360 mA output current range, while also providing equal system cost and substantially improved performance and energy efficiency.To prevent dangerous malfunctions, a 700 V power MOSFET and thermal shutdown circuitry is integrated onto a monolithic IC with The LNK304 devices. Since the voltage at the DRAIN pin directly powers the startup and running voltage for buck and flyback converters, they can operate without bias supplies and their accompanying circuitry.The LNK304 and 306’s model are integrated with an auto-restart circuit to prevents an excessive amount of power from being delivered to the output during short-circuit or open loop faults, as it lowers component count and system-level load protection cost. A local supply from the IC is available to employ an unsafely graded optocoupler to serve as a level shifter in buck and buck-boost converters, which aids in line and load control performance.

Features
