My MP2617HGL-Z the output voltage drops to 2V after powered on for 4 seconds, Anything perticular i should look for
(there is no short in the load)
Hello,
Are you able to confirm that you are following the typical application schematic as shown:
Please provide more information as well. Waveforms can help with this.
I followed the exact schematic
In the other thread, I provided the EVB schematic. Can you provide waveforms showcasing when this occurs assuming you can replicate this issue (SW Node, Vsys, etc)?
Is there some load change when this behavior occurs? When you add more capacitance (as suggested by the EVB schematic in another post) are there any changes after this? Is your inductor saturating?
the load 4G module. Its a heavy load around 2A peak surges when it tries connect to the network but in our other board this ic worked flawlessly only in this board it didnt work it is abnormal issue
Try adding multiple capacitors as seen in the EVB schematic in an effort to minimize the ESR of the Cin, Csys, and Cbatt capacitance rails. Let us know if this has some meaningful effects.
