Part Number: UCD9244 Other Parts Discussed in Thread: TMS320C6678 We are doing power cycle reliability testing on our TMS320C6678 design which uses a UCD9244 controller to bring up CVDD, 1.0V, 1.8V, and 1.5V (one accepted power-on sequence order according…
Here's the config file I'm using. One more note: the current spikes that I see during the soft start happen at very regulatr 100 us intervals (10KHz).
