Power Integrations, Inc. PMIC - PMIC - AC DC Converters, Offline Switchers - LNK520GN-TL LNK520GN-TL

The LNK520GN-TL is a member of the LinkSwitch family designed for low-cost AC-DC converters, specifically optimized for applications requiring constant voltage (CV) or constant voltage/constant current (CV/CC) solutions. It operates efficiently with a universal input range of 85-265 VAC and features a built-in 700 V power MOSFET, PWM control, and thermal shutdown circuitry, all integrated into a single monolithic IC. This device is particularly suitable for applications such as chargers for portable electronics, LED lighting, and auxiliary power supplies, with a maximum output power of 5.5 W. The LNK520GN-TL boasts energy efficiency, consuming less than 300 mW at 265 VAC input with no load, and meets various energy efficiency standards including California Energy Commission (CEC) and Energy Star requirements. The product includes features such as auto-restart for fault protection, reduced electromagnetic interference (EMI) due to its optimized switching characteristics, and a significant reduction in component count compared to traditional linear transformer solutions. It is designed to simplify circuit design while maintaining high performance and reliability, making it a viable option for engineers looking for cost-effective power supply solutions.
