Hi,
My customer has question about TPS55330 and TPS55340.
Could you tell me about questoin?
[Question]
My customer designed TPS55330 and TPS55340 under the following condition by WEBENCH.
Vin=3.6V to 4.2V
Vout=5.5V
Iout=0.3A
But design cannot be created with this device. The reason is "This design is not stable due phase margin".
My customer also tryed to design by Excel calcuration tool. Please show attached file.
(Please visit the site to view this file)
My customer think the device has phase margin.
Why the design is not stable by WEBENCH design?
Best Regards,
tateo
