Instructions for Using ACT30AHT
Input Connection:
- Connect the input voltage (VIN) to the positive terminal of the power supply.
- Ensure the input voltage is within the specified range (2.7V to 5.5V).
Output Connection:
- Connect the output voltage (VOUT) to the load.
- The output voltage is fixed at 3.3V.
Ground Connection:
- Connect the ground (GND) pin to the common ground of the system.
Thermal Considerations:
- Place the device on a heatsink or a PCB with adequate copper area to dissipate heat, especially under high load conditions.
- Monitor the operating temperature to ensure it does not exceed 125°C.
Capacitors:
- Use input and output capacitors as recommended by the datasheet to stabilize the voltage and reduce ripple.
- Typical values are 10μF ceramic capacitors for both input and output.
Protection:
- The device includes thermal shutdown protection to prevent damage from overheating.
- Ensure proper ventilation and cooling to avoid prolonged operation at high temperatures.
Testing:
- Before connecting the load, test the output voltage with a multimeter to ensure it is stable and within specifications.
- Gradually increase the load to the maximum rated current (30A) to verify performance.
Storage:
- Store the device in a dry environment with temperatures between -65°C and 150°C to maintain its integrity.
By following these instructions, you can ensure reliable and efficient operation of the ACT30AHT.
