Instructions for Using TPS23751PWPR
Power Supply Connection:
- Connect the input power supply (VIN) to the device within the specified operating voltage range (4.5V to 60V).
- Ensure the power supply is stable and capable of providing the required current.
Enable Pin (EN):
- The EN pin controls the operation of the device. Apply a high signal (≥1.2V) to enable the device.
- Apply a low signal (≤0.8V) to disable the device and turn off the output.
Output Load:
- Connect the load to the output pin (OUT). The maximum continuous output current is 6A.
- Ensure the load does not exceed the overcurrent protection threshold (6.6A) to avoid triggering the OCP.
Thermal Management:
- The device has built-in thermal shutdown to protect against overheating. Ensure adequate heat dissipation to keep the junction temperature below 160°C.
- Use a heatsink or other cooling methods if necessary, especially under high current conditions.
Short-Circuit Protection:
- The device includes short-circuit protection to prevent damage in case of a short circuit at the output.
- If a short circuit occurs, the device will automatically shut down and attempt to restart after a brief delay.
Operating and Storage Temperature:
- Operate the device within the ambient temperature range of -40°C to 125°C.
- Store the device within the temperature range of -65°C to 150°C.
Layout Considerations:
- Place the device close to the load to minimize trace inductance and improve performance.
- Use wide, short traces for power and ground connections to reduce resistance and inductance.
Capacitors:
- Use appropriate input and output capacitors to filter noise and stabilize the power supply.
- Recommended values and types of capacitors should be selected based on the specific application requirements.
By following these instructions, you can ensure reliable and efficient operation of the TPS23751PWPR.
