I am using DC/DC Module TPS62590 in my design. When I set the PDN analysis in Allegro, it requires slew indcance (Lsew), Flat Resistance (Rflat), Output inductance (Lout), Output Resistance (Ro). I was not able to get the info directly from the data sheet. I referred "Power Distribution System Design Methodology and Capacitor Selection for Modern CMOS Technology": To calculate Lslew, I must know the maximum transient current dI and the total amount of time dt for the TPS62590 to ramp this transient current either up or down.My question is: How can I derive these values, dI and dt, from the datasheet or from transient model?
Thanks and Regards,
