Overview
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
- Typical 9V/12V Output supplied from low input voltage source
- 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°C hysteresis)
- 1x MCP1663 9V/12/24V Output Boost Regulator Evaluation Board (ADM00664)
