Tool/software: WEBENCH® Design Tools
Hi,
Based on WeBench I've build the following schematic and layout. The input voltage range is 30-60V (lipo battery) and the output I aim for is 5V/10A.
PB1 (EN pin) is pulled to 5V by a microcontroller.
The problem is that the LM5116 doesn't seem to power on at all. I've supplied 32V to Vin from a lab bench power supply and probed, with an oscilloscope, Vout and the gates of the mosfets and all were 0V.
I'm fairly certain that this is not a soldering error, but I can't figure out what the chip doesn't power on.
General feedback about the schematic or layout is welcome since this is my first "power" related pcb.
