Hi,
We designed our own board which uses a LM27403 (schematics attached) to generate 0.9V @ 10 Amps. The input supply is 12V DC. What we notice is when we power the board, the LM27403 goes into a Fault state - we can observe the PGOOD signal pulsing. We are not using the DCR sensing to monitor current but instead using a series resistor. Would it be possible to provide some pointers as to what could be the issue?
thanks
