Other Parts Discussed in Thread: LM5050-1
Use three SMPSs in parallel. Each SMPS produces an output of 26.5V/20A.
We are expect to produces 26.5V/60A in three parallel mode.
If Load is between 21A and 40A, Two pairs of SMPS operate normally.
When Load over 40A, We are expect to operate 3 pairs of SMPS operate normally, But Some symptom appears.
The gate voltage of the two LM5050Q rises to 33V (appears to be working normally), But The gate voltage of one LM5050Q rises to 28V (appears to be not working).
SMPS it works when tested one by one.
Above picture is our PCB artwork.
We think LM5050Q1 not working that PCB pattern lt length to LM5050Q is different.
Is there a problem if the LM5050Q1 Vs pattern lengths differ in the SMPS generating the same output?
