TPS2373-4EVM-758: Transient Response

Part Number: TPS2373-4EVM-758

Hello,

The output transient in the user guide is pretty large (~750mV/5V = ~15%), is fc just very low or is this just expected for this kind of design? 

Thanks,

Michael

  • Hi Michael, 

    Thank you for your question. 

    It looks like there is a typo in that the figure shown says 7A to 14A transient but looking at the 5A/div this Figure is showing the transient response from 1.4A to 14A. 

    When we spec our EVMs, we aim to hit <15% p-p from 10% to full load transient so this is expected behavior. 

    Of note is that this transient is not common in most applications, the load transients are usually much slower than that. We take this measurement to show that even with an aggressive transient there is no instability. 

    Best Regards,
