Power Integrations, Inc. Specialized ICs - CAP006DG-TL CAP006DG-TL

The CAP006DG-TL is a specialized integrated circuit designed for automatic discharge of X capacitors in AC applications. It features a zero-loss operation, blocking current through discharge resistors when AC voltage is present, and automatically discharging the capacitors when the AC supply is disconnected. This functionality simplifies EMI filter design by allowing the use of larger X capacitors, which can reduce the size of inductive components without increasing power consumption. The device operates with a maximum total X capacitance of 2 mF and has a breakdown voltage rating of 825 V. It is self-supplied, requiring no external bias, and offers high common mode surge immunity with a differential surge withstand capability of 1000 V. The CAP006DG-TL is suitable for applications such as ACDC converters, appliances needing compliance with EuP Lot 6, and adapters that require ultra-low no-load consumption. The IC is housed in an 8-SOIC package, making it suitable for surface mount applications. It meets safety standards, allowing placement before or after the system input fuse, and provides over 4 mm of creepage on the package and PCB. The device is designed for low standby power consumption, with less than 5 mW at 230 VAC, making it an efficient choice for energy-sensitive applications.
