  • RE: TPS63021: VOUT voltage when PG output becomes low impedance

    Hi Shinichi, ・The minimum value and deviation of the threshold voltage regarding the VOUT voltage when changing PG output(L to H and H to L). R: we do not have such data. sorry. ・The status of the PG terminal, below the startup voltage(1.5V). R: If…

  • TPS63021: : Required Current 3.5A at buck and 2A at boost(Board sleep mode)

    TI Thinks Resolved
    Part Number: TPS63021 Hi Team, We are using TPS63021 buck boost regulator in our new design to generate 3.3V. There are two optional inputs battery and 5V supply, We require 3.3V/3.5A when input is 5v supply(need buck), also 3.3V/2A when input is con…

  • TPS63021: JZ | Shutting down output at currents above 2A

    Part Number: TPS63021 Hi, We have followed a recommended design from webench for a 3-4.2V to 3.3V @ 2.5A dc dc converter. The implemented design however will shut off the output whenever the current goes above 2A. We exchanged the recommended inductor…

  • TPS63021: Load disconnect when VIN < VOUT

    TI Thinks Resolved
    Part Number: TPS63021 Other Parts Discussed in Thread: TPS7H4010-SEP Hi, I have an application where we are thinking of using the TPS63021 and there will be times when VIN = 0V while VOUT = 3.3V because it is being provided by a second power source. …
