Overview
The MCP19035 600 kHz Synchronous Buck Converter Controller is a compact, highly efficient, step-down voltage converter that will convert the input voltage rail (typically 24V) to 5V regulated output voltage. The maximum output current for this step-down converter is 5A. The board demonstrates the capabilities of the MCP19035 600 kHz Synchronous Buck Converter Controller in a typical high-voltage input step-down application. Test points for various signals are provided for measuring different parameters of the converter. The reference design can be modified to support output voltages from 3.3V to 5V by changing a single resistor.
