TPS55386EVM-363

TEXAS INSTRUMENTS  TPS55386EVM-363.  评估板, TPS55386 可调 3A 非同步降压转换器

The is an evaluation module for TPS55383 dual non synchronous buck converter providing fixed 5.0V and 3.3V output at up to 3A each from a 12V input bus. The evaluation module is designed to start up from a single supply, so no additional bias voltage is required for start up. The evaluation module uses the TPS55386 600KHz Dual Non Synchronous Buck Converter with integral high side FET. The TPS55386EVM-363 is designed to use a regulated 12V +10% /-20% bus to produce two regulated power rails, 5.0V and 3.3V at up to 3A of load current each. The evaluation module is designed to demonstrate the TPS55386 in a typical 12V bus system while providing a number of test points to evaluate the performance of the TPS55386 in a given application. The evaluation module can be modified to other input or output voltages by changing some of the components.
