Hi Experts,
What kind of master/slave mode would you recommend if we are using only one IC in a board? Master or Slave?
We encounter an issue that we can possibly fix below issue if we set IC to master mode, we thought it may be caused by noise. What do you think of this issue.
CH2: phase 1 switching node, CH3:5V outout, CH4 : phase 2 switching node.
The TPS40322 cannot ramp up during load higher than 0.3A, but we can solve this issue when we reduce the switching frequency from 500k to 300k,
could you tell me why?
