Other Parts Discussed in Thread: CSD18540Q5B
Hello,
We are using LM5176 in out power supply. Vin is 48VDC Vout is 24V with 5.5A.
The circuit is similar to your webench design.
Power inductor is XAL1010-472MEB, Buck MOSFETs M1 & M2 are BSC340N08NS3-G, boost MOSFETs M3 & M4 are CSD18540Q5B.
The problem we are facing is, with no load the inductor is getting very hot. if we connect small load, the LM5176 blows. BOOT1 (pin 26) getting short with AGND.
Please let us know how to solve this problem?
Our circuit diagram is shown below,
