Re: EN6337QA SPICE model
Hello @CEHymowitz , Thanks a lot for your feedback. As i can notice that the orange model that you compare with is not from the stability tool that i attached which has a closer impedance to your measurement. As i explained in my previous response, that the stability tool will check all the circuit variation and corner cases when you click the compensate button. Attached are an encrypted pspice DC (time domain) and AC(frequency domain) models to simulate EN6337 in PSPICE environment. Thanks, MostafaRe: EN6337QA SPICE model
Hi @CEHymowitz , I am sorry, i can't share un-encrypted model due to the model related confidential information. I will create the AC model for you, but need some time. Whatever, the LTSPICE model and the stability tool are accurate to represent EN6337, but the stability tool presented bode plot maybe is not same as what you measure where the present bode plot at the nominal case but when you click the compensate button the tool will check all the other corner case. I have enabled the Zout_closed loop model on the attached stability tool, please check IND_Ripple tab. Please note that EN6337 has a soft inductor and the inductance value will change based on the loading current. So the LTSPICE model is very good to model the DC analysis and the stability tool will help to adjust the loop to make sure the VR is stable.

Hello @diverger , Here is the answer for your points: You don't need the GUI for Rtune calculation, you can calculate the RTUNE based on table 11 at the datasheet pg 22 you can share your output capacitor and i will help to calculate the Rtune value you can also use that attached stability tool to calculate the Rtune There is no any difference between L01 and L02 parts and also if you don't need the PMBUS on production you can use EM2030 which cheaper in price https://www.intel.com/content/dam/altera-www/global/en_US/pdfs/literature/ds/em2030qi_13356.pdf L01 will be NRND where there is no many customer use it and L02 is fully compatible with L01 Pok is push pull for L01 device regardless the PMBUS address Regards, MostafaRe: EP5348UI Reliability and Enivorment compliance

Hello @diverger, EM2130L01 is the same as EM2120L02 but has older FW and the POK signal is push pull configuration only. EM2130L02 is the newer FW and has both POK push pull or open drain configuration and selected based on the PMBUS address. Please check the datasheet page 20 under POWER OK section. https://www.intel.com/content/dam/altera-www/global/en_US/pdfs/literature/ds/em2130l02_12873.pdf Could i know what parameters you would like to calculate for EM2130L01?
