Hi,
I am doing a 30Vout, 0.435Aout Buck, with von = 38V.
It uses TPS57040.
None of the 10 prototypes have worked. One of the boards did work, but regulated to 26.5Vout instead of the 30V that the divider was setting it to...strangely, this board wouldnt work at all when i changed the compensation resistor from 133k to 10k (the compensation C , in series with it. was 10nF).
I am not using any ESD precautions as there are none available. The floor i am standing on is linoleum.
