Other Parts Discussed in Thread: CSD18540Q5B
Tool/software:
Hello. I am very new to the SMT world. Trying to build my first buck converter for our applications. I am using LM5145 IC. 2 x CSD18540Q5B mosfets and Inductor. (schematic attached). I have 0 output with load. With no load output slowly rises to about 4.4 volts.
Vin - 30 v
Vout - should be 16V
VCC -7..5 volts.
EN/UVLO - 13.9 volts.
Comp output 4.9V
FB - 0.2 Volts (190 kOm Tor res, 10 kOm Bottom res)
so the IC is not switching HI Mosfet.
Any ideas why?
