CSD95420RCB中文资料50-A peak continuous synchronous buck NexFET™ smart power stage数据手册TI规格书

描述 Description

The CSD95420RCBNexFET™ power stage is highly optimized for high-power, high-density synchronous buck converters. This product integrates the driver device and power MOSFETs to complete the power stage switching function. This combination produces high-current, high-efficiency, and high-speed switching capability in a small 4 mm × 5 mm outline package. The device integrates the accurate current sensing and temperature sensing functionality to simplify system design and improve accuracy. The optimized PCB footprint helps reduce design time and simplifies the completion of the overall system design.
