  • TPS63020: Clarification required on the simplified schematic in the datasheet "TPS63020".

    TI Thinks Resolved
    Part Number: TPS63020 In TPS63020 datasheet the sample schematic show that the EN pin #12 is connected to GND through the capacitor C3. Then in the WEBENCH Power Designer also displays the same schematic as in the datasheet. (i.e) EN pin #12 is connected…

  • RE: TPS63020: Does LDO at the o/p of TPS63020 necessary for powering the RF Modules

    Resolved
    Hi Raghavendra, Under those conditions you can expect around 5 mVpp ripple in PWM mode, and at most 90 mVpp outout voltage ripple in PFM (power save) mode. This is valid for our TPS63020EVM-487, and the output capacitors we have there. If you are using…

  • RE: TPS63020: tps63020

    Resolved
    I just received a TPS63020EVM-487 and tried it. The output is not steady, fluctuates about 50mV with the power save mode. The output is stable when it is not in the power save mode. The voltage is around 3.44V when in the power save mode and 3.29V when…

  • TPS63020: question of use of TSP63020 for driving Peltier element

    Resolved
    Part Number: TPS63020 Other Parts Discussed in Thread: PMP9759 , We are building a Peltier driver based on http://www.ti.com/tool/PMP9759 . Our test circuit is not stable. We notice that the stability improves if low-impedance Peltiers are used (thus higher…

  • RE: TPS63020: Maximum allowable ESR for CIN and COUT?

    Resolved
    Hi Milos, Thanks for the reply. I don't expect significant load transients, and efficiency isn't too important for me either. 25 mVpp is the DC ripple specification. Unfortunately I am limited to a single 1206 on CIN and COUT due to PCBs already…
