8.3 Do's and Don'ts

  • Don't: Exceed the Absolute Maximum Ratings.
  • Don't: Exceed the ESD Ratings.
  • Don't: Exceed the Recommended Operating Conditions.
  • Don't: Allow the EN or MODE input to float.
  • Don't: Allow the voltage on the EN or MODE input to exceed the voltage on the VIN pin.
  • Don't: Allow the output voltage to exceed the input voltage.
  • Don't: Use the thermal data given in the Thermal Information table to design your application.
  • Do: Follow all of the guidelines and suggestions found in this data sheet before committing your design to production. TI Application Engineers are ready to help critique your design and PCB layout to help make your project a success.
  • Do: Refer to the helpful documents found in Table 11-1 and Table 11-2
