Instructions for Using AXP223
Power Supply Connection:
- Connect the input power supply (2.7V to 5.5V) to the VIN pin.
- Ensure the input voltage is within the specified range to avoid damage to the device.
Output Configuration:
- Set the desired output voltage using the external resistor divider connected to the FB (feedback) pin.
- The output voltage can be calculated using the formula: ( V_ = V_ times left(1 + fracright) ), where ( V_ ) is typically 0.8V.
Enabling the Device:
- To enable the device, connect the EN (enable) pin to VCC or a high logic level.
- To disable the device, connect the EN pin to GND or a low logic level.
Thermal Management:
- Ensure adequate heat dissipation by providing a thermal pad or heatsink if the device is expected to operate at high power levels.
- Monitor the temperature to ensure it does not exceed the maximum operating temperature of 150°C.
Protection Circuits:
- The AXP223 includes built-in overcurrent, short-circuit, overvoltage, and thermal protection circuits.
- In case of a fault, the device will automatically shut down to prevent damage.
Layout Considerations:
- Place the input and output capacitors as close as possible to the respective pins to minimize noise and improve stability.
- Use a ground plane to reduce parasitic inductance and improve thermal performance.
Testing and Verification:
- After assembly, verify the output voltage and current using a multimeter.
- Test the device under various load conditions to ensure it meets the required specifications.
Storage and Handling:
- Store the device in a dry environment to prevent moisture damage.
- Handle with care to avoid static discharge, which can damage the sensitive components.
By following these instructions, you can ensure the AXP223 operates reliably and efficiently in your application.
