TPS61022: Continuous Output Current

Part Number: TPS61022
Other Parts Discussed in Thread: TPS61288,

Tool/software:

Hi Teams, 

My customer is seeking the boost solutions with small package but can sustain higher current. 

Design Requirements:

  1. Smaller package is preferable
  2. Boost from 1S battery to 5V --> 3V or 3.3V to 5V
  3. Can sustain at least 6A continuous output current(5A for USB port and 1A for system use)
  4. Sustain 6A without trigging any protection mechanism( e.g. OVP, OTP, OCP). 

They are now surveying TPS61022RWUR but when Vin is 3.3V and they can't make sure if the output current can really go up to 6A and will not trigger OTP or other protection mechanism when the efficiency is truely low.

Thanks!

    Hi Gary,

    The 6A output current is too large to support for TPS61022. You could promote TPS61288, it can support 3V to 5V/6A.

    What is the max ambient temperature in the application? It is related to that if the OTP is triggered.

    Regards,
