[FAQ] How should I select the right PMIC for my application?

Other Parts Discussed in Thread: TPS65023B, LP87561-Q1

How should I select the right PMIC for my application?

  • Selecting the right multi-rail integrated power management integrated circuit (PMIC) can be a daunting task, but there are some tools available which can help to point you in the correct direction.

    Generally, the key characteristic for a PMIC is what is being powered. If it is an application processor or an automotive camera module, there are often pre-defined solutions. A great resource for these is the PMIC landing page, which has information divided by application and processor as well as a parametric search table of released parts.

     

    If these are not able to help you find the ideal PMIC, please be sure to include the following information when requesting advice:

    • A block diagram of the system if available
    • Input voltage
    • All output voltages
    • All output currents (max)
    • Number of specific regulators required, like buck converters or linear regulators
    • Package restrictions (i.e. is QFN required or is DSBGA ok?)
    • Whether automotive grade is required
    • Optional: total quantity of boards being built
      • Parts like the TPS65023B can be hardware configured to have any default voltage / sequence, however others like the LP87561-Q1 require software configuring after power up or factory programming of the memory. Factory programming requires minimum business case requirements and should be discussed with your local TI sales contact.
