I try to use TPS659113 to power up am3874. My external FETs are CSD16325Q5, Input voltage is 5V. All dc-dc converters (VDDs, VIO, LDOs) work the same way as in MISTRAL EVM board, i2c connection works. But VCCctrl module not good, much noise in output and output capasitor heated. Maybe i forgot to configurate something?
