Dear Specialists,

I tried to simulate TPS563201 4.5-5.5 Vin, 3.3Vout 3A in WEBENCH, but I couldn't.

According to the datasheet, it should operate under the condition.

I think it's a bug.

if so, I would be grateful, if you could fix.

I appreciate your great help in advance.

Best regards,

Shinichi

When the VIn=4.5, the duty cycle will exceed the limit in the full load, so if you set the Vin=5V, it will be OK.

Hi Vental,

Thank you for your reply.

I understand the current at Vin 4.5V is the problem.
This is a problem of device spec, not webench.

I appreciate your great help.

Best regards,
Shinichi
