Other Parts Discussed in Thread: TPS62A02

Hi TI Technical Team,

I have used TI Buck converter, one of the Design.

TI IC used: TPS62A06DRL

Input Voltage: 5.1V

Output required: 3.8V and 3A

I am getting 0.71V output as per simulation in WEBENCH^® POWER DESIGNER .

please refer me some design Idea or issue.

Hi Saurav,

I'm not sure if I understand your issue correctly.

The selected feedback divider in the schematics should result in a 3.8V output voltage.

In the title your are mentioned the TPS62A06A device which has a max. Iout of 6A.

In your schematic you are using the TPS62A02 version which is limited to 2A max and will not fulfill your requirement of 3A.

Where are you getting 0.71V, in WEBENCH or on your board? Which device you are using?

Best regards, Sepp
