  • TPS54290: PGND1 and PGND2 connection

    Resolved
    Part Number: TPS54290 Hi, My customer is looking for a two channel buck to supply C2000 MCU. It's 12-to-3.3V application. MCU has two grounds - AGND and DGND - which connect to each other thru a 0ohm resistor for noise minimization. I'm wondering if…

  • TPS54290: TPS54290PWP - How to set Vout2 = 5V/2.5A

    TI Thinks Resolved
    Part Number: TPS54290 Other Parts Discussed in Thread: TPS54291 Dear Sir/Mam, Good Day. I would like to know that for Buck IC TPS54290PWP. Datasheet mention two output 1) 3.3V/1.5A 2) 1.2V/2.5A I would like to change second output Vout = 1.2V/2.5A to…

  • RE: TPS54290: Not getting Out2 as expected

    John, Thank you for supporting Bhupendar on this issue. He is working on my board design and the TPS54290 looked like an ideal part for our prototype but we will not be able to use it for production or any future design if we cannot figure out how to…

  • RE: TPS65279: current limiter accuracy

    Hi Vincenzo, The peak current limit can't be set to value lower than 5A with acceptable variation. How much Iout do you need? TPS65261 (3A/2A/2A triple buck) or TPS54290 (1.5A/2A dual buck) seems to be better for your application. Any further need…
