Instructions for Use

1. Circuit Design:

   • Ensure the input voltage is within the specified range (4.5V to 28V).
   • Use appropriate external components such as inductors and capacitors to set the output voltage and filter the output.

2. Output Voltage Adjustment:

   • The output voltage can be adjusted using an external resistor divider connected to the feedback pin (FB).
   • Calculate the resistor values using the formula: [ V_{text} = V_{text} left(1 + fracright) ] where ( V_{text} = 0.8V ).

3. Thermal Considerations:

   • Ensure proper heat dissipation by providing adequate copper area on the PCB.
   • Use a heatsink if necessary, especially for high-output current applications.

4. Power-Up Sequence:

   • Apply the input voltage slowly to avoid inrush currents.
   • Ensure the input voltage is stable before enabling the output.

5. Shutdown Mode:

   • To put the device into shutdown mode, pull the SHDN pin low.
   • The device will consume minimal current in this mode.

6. Protection:

   • The PM5352-BI has built-in overcurrent, overtemperature, and undervoltage lockout protection.
   • Do not exceed the maximum ratings to prevent damage to the IC.

7. Storage and Handling:

   • Store the IC in a dry, cool place.
   • Handle with care to avoid static damage. Use ESD protection when handling the IC.
