Power Integrations, Inc. PMIC - PMIC - AC DC Converters, Offline Switchers - LNK362DG LNK362DG

The LNK362DG is part of the LinkSwitch-XT family of offline switcher ICs designed for energy-efficient, low-power applications. It features a proprietary design that allows for clampless operation, reducing system costs and component count while enhancing efficiency. The device integrates a 700 V power MOSFET, an oscillator, and a simple ON/OFF control scheme, eliminating the need for a bias winding and associated components. This IC provides robust protection features, including auto-restart for short-circuit and open-loop conditions, accurate thermal shutdown, and frequency jittering to minimize electromagnetic interference (EMI). It operates over a universal input range of 85-265 VAC and is suitable for various applications, such as chargers for portable devices and power supplies for appliances and industrial systems. The LNK362DG achieves low no-load consumption, making it compliant with global energy efficiency regulations, and is characterized by a high bandwidth for fast turn-on and excellent transient load response. Its low component count contributes to higher reliability and simplified PCB design.
