ADM00467

The ADM00467 from Microchip is a MCP16311/2 synchronous buck converter evaluation board. The MCP16311/2 synchronous buck converter evaluation board is used to evaluate and demonstrate Microchip Technology’s MCP16311/2 product. This board demonstrates the MCP16311 (PFM/PWM low quiescent current) and the MCP16312 (PWM low output voltage ripple) in two buck converter applications with two output voltages. It can be used to evaluate 8LD MSOP and 8LD 2 x 3 TDFN package option. The MCP16311/2 synchronous buck converter evaluation board was developed to help engineers reduce the product design cycle time. 3.3V and 5V two common output voltages can be selected. The first converter with the 8LD MSOP package is a PWM/PFM device with a fixed output of 3.3V, while the second converter with the 2 x 3 8LD TDFN package is a PWM-only device with a fixed output of 5V.

• Input voltage range (VIN) from 4V to 30V
• Output current is typically 1A at 3.3V output, 12V input
• PWM switching frequency is 500KHz
• Internal compensation
• Internal soft start
• Overtemperature protection (if the die temperature exceeds +150°C, 25°C hysteresis)
