LM5030: Output Capacitor Calculation

Nesh Johny

Part Number: LM5030

Dear Sir,

Can you suggest any reference document for Output capacitor calculation for the load Transient conditions like 0% to 50%/100% in Push Pull converters and current Fed push pull converters.

Hello Nesh,

One method you can use to calculate the output capacitance is to assume the output capacitor has to hold up or maintain the output voltage during the transient.

This gives you

Cout = I*T/DeltaV

Where I is the load current, Delta V is the allowed change in output voltage and T is the duration of the transient response.

Attached is a TI application document that explains in further detail.
