Part Number: LM5041

Dear Sir,

Could you please share the specification output ripple % considered for the output 2.5V 50A in LM5041EVAL board.

how is the output capacitor value calculated 932uF (Total Output capacitance) with required ESR.

Thanks & Regards,

Nesh

dear Johny,

EVM board output capacitance value is reference for you. To selecting output capacitor, you need to consider output current ripple, temp, hold up time and so on.
