  • [FAQ] LM26480: Is there a reference design of power up sequence implemented by RC delay on EN pin?

    Phil Yi40
    Phil Yi40
    Part Number: LM26480 Yes; a set of RC (Resistor and Capacitor) values were used on TI LM26480 EVM with VCC=3.3V on 3 "EN" pins (ENSW2, ENLDO1, ENLDO2) to control the power up delay for the sequence. ENSW1 connects to VCC directly without RC delay…

    Part Number: LM26480 Is there a reason why even before the Enable pins are asserted for both of the bucks, nPOR is high? I.e. Why is nPOR high before t0?

  • LM26480: Plan to tie EN to Vin, do I still have to worry about the 8ms delay?

    Resolved
    Part Number: LM26480 Do we need an RC to make sure the delay is happening? I saw another post where they recommend a 1uF cap but I don't think the trace resistance will be high enough to achieve 8ms delay.
