MCP1663 9V/12V/24V Output Boost Regulator Evaluation Board

The MCP1663 Evaluation Board is used to evaluate and demonstrate Microchip Technology’s MCP1663 step-up switching regulator. This board comes with two distinct applications. The 1st circuit can be used to evaluate the MCP1663 in the typical boost configuration 9V/12V selectable output. The board also provides an example of how a higher input voltage application can be implemented.

• MCP1663 device can be evaluated in two separate applications:
      
  • Typical 9V/12V Output supplied from low input voltage source    
            
    • Input Voltage range (VIN): 2.4V to 5.5V, with VIN < VOUT
            
    • Output Current: typical 250 mA @ 12V Output, 3.3V Input
            
    • Enable state selectable using EN switch
        
        
      
  • 24V Output supplied from high input voltage source    
            
    • Input Voltage range (VIN): 9V to 16V
        
        
• Undervoltage Lockout (UVLO)
      
  • UVLO Start: 2.3V
      
  • UVLO Stop: 1.85V
• PWM Operation
• PWM Switching Frequency: 500 kHz
• Peak Input Current Limit of 1.8A (typical)
• Internal Compensation
• Soft Start
• Protection in case of feedback pin shorted to GND
• Overtemperature Protection (if the die temperature exceeds +150°C, with 15°Chysteresis)
