Part Number: LM5121

Hi team,

would you please share a offline design tool for LM5121? My customer is trying to improve transient response by increase output cap and worry about stability of the device. it is hard to run this kind of simulation on WEBENCH, thanks.

    Hi Kevin,

    We don't have such tool yet. You may refer to the LM25122 calculator help you select the compensation network. The LM5121 and LM(2)5122 share the same PWM controller circuit.

    Use this tool to get a good start point. Then, when you built the circuit, fine tune the loop compensation by experiment.  You will have to measure the loop anyway.

    Thanks,
