Power Integrations, Inc. PMIC - PMIC - AC DC Converters, Offline Switchers - LNK585DG-TL LNK585DG-TL

The LNK585DG-TL is an integrated off-line switcher designed for AC to DC conversion, featuring a flyback topology with a typical operating frequency of 100 kHz. It supports an output power of up to 4.5 W at 230 VAC and is suitable for both isolated and non-isolated applications. The device boasts zero standby consumption, with power-down mode consumption measured at less than 3 mW, making it compliant with global energy efficiency regulations. Key features include hysteretic thermal shutdown protection, auto-restart functionality during fault conditions, and a simple ON/OFF control mechanism that eliminates the need for loop compensation. The internal oscillator frequency is jittered to minimize electromagnetic interference (EMI), which can reduce the cost of external filtering components. The LNK585DG-TL is packaged in a compact SO-8C format, enhancing its suitability for low-cost designs while maintaining high reliability in various applications.
