Instructions for Using TPS23753APWR

1. Power Supply Connection:

   • Connect the input power supply (VIN) to the appropriate pin.
   • Ensure the input voltage is within the specified range (4.5V to 60V).

2. Output Configuration:

   • The output voltage (VOUT) will be the same as the input voltage (VIN).
   • Connect the load to the VOUT pin.

3. Enable Pin:

   • Apply a voltage between 1.2V and 15V to the enable pin (EN) to turn on the device.
   • If the enable pin is left floating or grounded, the device will be in a low-power state.

4. Thermal Management:

   • Ensure adequate heat dissipation to keep the junction temperature below 150°C.
   • Use a heatsink if necessary, especially under high load conditions.

5. Fault Protection:

   • The device has built-in fault protection that will shut down the output if a fault condition is detected.
   • The fault response time is typically 2.5μs.

6. Operating Temperature:

   • The device can operate in ambient temperatures ranging from -40°C to 125°C.
   • Store the device in temperatures between -65°C and 150°C.

7. Quiescent Current:

   • The quiescent current is typically 80μA and can go up to 120μA.
   • This current is drawn even when the device is not supplying any load.

8. Load Current:

   • The maximum continuous load current is 5A, with a typical value of 1.5A.
   • Ensure the load does not exceed this limit to avoid damage.

9. Layout Considerations:

   • Use short and wide traces for power connections to minimize inductance and resistance.
   • Place decoupling capacitors close to the input and output pins to improve stability and reduce noise.

10. Storage and Handling:

    • Store the device in a dry environment to prevent moisture damage.
    • Handle the device with care to avoid static discharge, which can damage sensitive components.
