LM51772: output capacitor

Part Number: LM51772


Hi,

We have queston about the LM51772.

For EVM output cap C13, could we change to MLCC 10uF *3?

Thanks!

    Hi Jeff,

    sure you can also use some MLCC capacitors to get the required output capacitance but please consider the DC BIAS of MLCC to get the effective Capacitance used.

    This is required to ensure output ripple voltage meets your requirement and also for loop stability calculation.

    Best regards,
