"IR11682S 英飞凌芯片 INFINEON 中文版规格书手册.pdf详解"

The IR11682S is a dual SmartRectifierTM driver IC manufactured by Infineon Technologies. The IC is designed to serve as a secondary-side high-speed controller for synchronous rectification in resonant half-bridge topologies. One of the key features of the IR11682S is its use of a 200V proprietary IC technology, which ensures efficient and reliable operation. With a maximum switching frequency of 400KHz, the IC can handle high-speed switching applications. This allows for improved efficiency and reduced power loss in resonant half-bridge circuits. The IR11682S also incorporates anti-bounce logic and undervoltage lockout (UVLO) protection. The anti-bounce logic helps in eliminating any unwanted oscillations or noise during switching transitions, ensuring smooth and stable operation. The UVLO protection feature monitors the input voltage and prevents the IC from operating when the input voltage falls below a certain threshold. This ensures safe and reliable operation of the IC. Another important feature of the IR11682S is its 4A peak turn off drive current capability. This high peak current allows for fast and efficient switching of the high-power MOSFETs used in the synchronous rectification circuit. This helps in minimizing switching losses and improving overall efficiency. In addition, the IR11682S includes a micropower start-up feature, which enables the IC to start up with minimal power consumption. This is particularly useful in applications where energy efficiency is critical. Overall, the IR11682S is a highly capable dual SmartRectifierTM driver IC that offers a range of features to enhance the performance and efficiency of synchronous rectification in resonant half-bridge topologies. With its high-speed switching capability, anti-bounce logic, UVLO protection, and high peak turn off drive current, the IC provides a reliable and efficient solution for power electronics applications.
