ADM00445

ADM00445 is a MCP19035 600kHz synchronous buck controller evaluation board. This is a compact, highly efficient, step-down voltage regulator that will convert the input voltage rail (typically 12V) to 1.8V regulated output voltage. The maximum output current for this step-down converter is 10A. The board demonstrates the capabilities of the MCP19035 600kHz synchronous buck converter, as well as Microchip’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 0.9V to 3.3V by changing a single resistor.

• Input voltage range from 8V to 14V
• 1.8V output voltage (can be adjusted by changing one resistor between 0.9V and 3.3V)
• 10A maximum output current
• 88% typical efficiency at 1.8V/10A
• 600kHz fixed switching frequency
• On-board high-performance power MOSFET transistors
• Overcurrent protection for high and low-side MOSFETs
• Power Good output for monitoring the output voltage quality
• Shutdown input for placing the converter in low-power Standby mode
• Under Voltage Lockout (UVLO) with 4.2V and 3.6V typical thresholds
