  • TPS7B4253-Q1: Enable pin troubles

    Resolved
    Part Number: TPS7B4253-Q1 Other Parts Discussed in Thread: TPS7B4253EVM , , TINA-TI Hello! We are seeing a strange startup behavior when using the ENABLE pin while ADJ is already stable. The setup is the TPS7B4253EVM: TP1 (VIN) = 24V power…

  • RE: TPS7B4253-Q1: Output Capacitor: Does data sheet mean Nominal Value or Effective Value?

    Resolved
    Hi Shota, The minimum output capacitor requirement of 10 uF is for the nominal value. Depending on your application requirements, you may wish to increase the output capacitor. We recommend prototyping your application and performing a worst case load…

  • RE: TPS7B4253-Q1: Acceptable Cfb(capacitor between out and FB pins) value

    Resolved
    Hi Shota, A feedforward capacitor can help improve stability, output noise, load transient response, and PSRR. As noted the TPS7B4253-Q1 recommends a 47 nF feedforward capacitor when the desired output voltage is greater than the reference. A 0.1 uF…

  • TPS7B4253-Q1: Dropout voltage vs output current

    Part Number: TPS7B4253-Q1 I have a couple of questions about this device tps7b4253-q1 1: In Figure 4: Dropout Voltage vs Output Current of datasheet, it is shown the voltage drop versus output current, @Vin=Vadj=4V I would like to have a plot @Vin=Vadj…
