TEXAS INSTRUMENTS CSD86350Q5DEVM-604 评估模块, 同步降压转换器
The evaluation module is a synchronous buck converter featuring "s NexFET power block technology to provide a high current, ultra high density power supply solution. The evaluation module provides a 1.2V output at 25A from a 12V nominal input bus at over 92% efficiency. The evaluation module is designed to operate from a single supply, so no additional bias voltage is required. The evaluation module uses the TPS51218 high performance, mid input voltage, synchronous buck controller and TI"s NexFET power block to optimize the efficiency and power density of the total solution. The evaluation module provides two test points for measuring the output voltage generated by the module. This allows the user to measure the actual output voltage without losses from output cables and connectors.
