MP3394S Instructions

1. Power Supply Connection:

   • Connect the input voltage (VIN) to the power supply.
   • Ensure the input voltage is within the operating range (4.5V to 18V).

2. Output Configuration:

   • Set the output voltage (VOUT) using external resistors connected to the FB pin.
   • The output voltage can be adjusted from 0.6V to 1.8V.

3. Enable Pin:

   • Connect the EN pin to a logic high (≥1.2V) to enable the controller.
   • Connect the EN pin to a logic low (≤0.8V) to disable the controller.

4. Switching Frequency:

   • Set the switching frequency (FSW) by connecting an external resistor to the RT pin.
   • The typical switching frequency range is 300kHz to 700kHz.

5. Current Limit:

   • The maximum phase current (IPHASE) is 20A per channel.
   • Use appropriate inductors and MOSFETs to handle the current.

6. Protection Features:

   • The controller includes under-voltage lockout (UVLO), overvoltage protection (OVP), and thermal shutdown (TSD).
   • Ensure the UVLO threshold (3.0V to 3.5V) is not exceeded.
   • The OVP threshold is set at 1.85V to 1.95V.
   • The thermal shutdown temperature is 150°C to 160°C.

7. Thermal Management:

   • Place the controller in a well-ventilated area or use a heatsink to manage heat dissipation.
   • Monitor the operating temperature to ensure it stays within the range of -40°C to 125°C.

8. Storage and Handling:

   • Store the device in a dry environment with temperatures between -65°C and 150°C.
   • Handle the device with care to avoid static damage.

By following these instructions, you can effectively configure and operate the MP3394S 4-Phase Buck Controller.
