TPS62400-Q1: Maximum Load Capacitance

Part Number: TPS62400-Q1

Hi There,

For the TPS62400-Q1 what is the maximum (low ESR, ceramic) capacitance that can be placed on output 1 of a TPS62400-Q1, when it’s set to 1.2 V and has a 2.2 uH inductor?

Does it matter if it is set for permanent PWM or if it’s allowed to go to PFM mode?

Thanks in advance for your help.

Regards,

Ross

    This is shown in the D/S at the bottom of pages 24 and 25. This IC uses voltage mode control, which has a small range of allowed Cout.

    With the very low currents supported by this IC, I don't an immediate reason for wanting to use more Cout. What design goal does more Cout help achieve?

    If the load is high enough that PWM mode is entered, even if PFM/PWM is selected, then the stability does not change between the modes. For lighter loads in PFM mode, stability is less of a concern.
