MICROCHIP ADM00445. 评估板, MCP19035 600KHZ同步降压控制器
The MCP19035 600 kHz Synchronous Buck Controller Evaluation Board is a compact, highly efficient, step-down voltage regulator that will convert the input voltage rail typically 12 V to 1.8 V regulated output voltage. The maximum output current for this step-down converter is 10 A. The board demonstrates the capabilities of the MCP19035 600 KHz Synchronous Buck Converter, as well as ’s high-performance power MOSFET transistors. Test points for various signals are provided for measuring different parameters of the converter. The evaluation board can be modified to support output voltages ranging from 0.9 V to 3.3 V by changing a single resistor.
