<p>The TPS53676 multiphase buck test with Infineon TDA21472 power stages is up and running. I've only tested with 20 A pulses from the onboard switched load and that looks very promising. I'll add a 50 A fixed load and retest with the load alternating between 50 and 70 A. I've not done much tuning yet, mostly defaults in the control loop but the load step response is impressive. There's a lot of flexibility.</p>
