  • LM27762: !PGOOD sink

    TI Thinks Resolved
    Part Number: LM27762 Hello, I am using a LM27762DSST and noticed that the !PGOOD open drain output doesn’t seem to be capable of sinking very much current. I have a circuit that wants to sink about 3.4 mA through that !PGOOD node, but it looks like…

  • LM27762: PGOOD Pin Operation

    TI Thinks Resolved
    Part Number: LM27762 Hi, I'm trying to understand the operation of the PGOOD pin on this device but I find the working of it confusing. Within the Pin Functions it says that Logic 0 = Power good, Logic 1 = power not good. I assume that this means…

  • LM27762: Output voltage ripple: mVpp?

    Resolved
    Part Number: LM27762 Hi team, Datasheet merely shows "mV" for Output Voltage Ripple as below. Just to make sure, does it mean mVpp(peak-to-peak)? (Or Rms?) Best regards, Shota Mago

  • LM27762: VOUT calculation

    TI Thinks Resolved
    Part Number: LM27762 Hello team, I am confused about the VOUT calculation equation. Which equation is correct? On datasheet, the positive VOUT is VOUT = 1.2 V × (R1 + R2) / R2. On the datasheet, negative VOUT is VOUT = –1.22 V × (R3 + R4) / R4…
