Description
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.
Features
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 < VOUTOutput Current: typical 250 mA @ 12V Output, 3.3V InputEnable 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: 2.3VUVLO Stop: 1.85V
PWM OperationPWM Switching Frequency: 500 kHzPeak Input Current Limit of 1.8A (typical)Internal CompensationSoft StartProtection in case of feedback pin shorted to GNDOvertemperature Protection (if the die temperature exceeds +150°C, with 15°C hysteresis)
