Other Parts Discussed in Thread: LMZ14203H

Hello all,

We are using LMZ14203H for converting 24v to 8.6v, and designed with the help of webench. We have also followed all PC BOARD LAYOUT GUIDELINES which is mentioned in datasheet.

Now i am getting respective voltage as below:-

1.Vin=24v

2.RON= 1.7V

3.EN= 2.4V

4.GND=0V

5.SS= 0.5V

6.FB= 0V

7.VOUT=0.4V.

We are facing this issue and not getting required 8.6v.

We need help in resolving the issue.
