TPS65910: AM335x GP EVM step-up DC/DC circuit error

Harvey Wang97

Part Number: TPS65910

Hi Sir,

In the schematic of AM335x-GPEVM,I found a mistake about the step-up DC/DC circuit of PMIC TPS65910.The device Pin31 provides one step-up converter,but it is a buck circuit construction in the reference design ,please help to confirm,many thanks!

Hi Harvey,

You are absolutely right, that is set up incorrectly. I'm moving this to the Sitara forums to let them know about the proper setup on the EVM.

Sitara team,

Can you help to add to your errata that the VDD3 step up schematic is not correct and fix it in any future revisions? You can reference the TPS65910EVM-583 for proper connection (direct link to user guide) or the datasheet. I know it isn't used in the GPEVM but it would still be good to at least show it connected properly.
