MCP16331 Buck Converter Evaluation Board (Part Number ADM00519)

The Microchip MCP16331 Buck Converter Evaluation Board is used to evaluate and demonstrate Microchip's MCP16331 product in the SOT-23 package. This board demonstrates the MCP16331 in a buck-converter application with two selectable output voltages. Test points are provided for input and output, allowing the board to be connected directly to a system. Additional test points are provided to access the EN pin in order to modify the state of the converter and to access the SW pin (to see the switching waveform). The MCP16331 High-Voltage Buck Converter Evaluation Board was developed to help engineers reduce product design cycle time. The MCP16331 is available on Microchip Direct.

Features

  • Input voltage range, VIN: 6V to 50V
  • Converter can be turned on/off by using a jumper on the EN/GND connector
  • Fixed output voltage: 3.3V or 5.0V (selectable through the use of a switch)
  • Typical output current: 500 mA
  • PWM switching frequency = 500 kHz
  • Internal compensation
  • Internal soft-start
  • Over-temperature protection (if the die temperature exceeds 150°C, 25°C hysteresis)
