Part Number: PSEMTHR24EVM-081 Other Parts Discussed in Thread: TPS23881EVM-083 , Tool/software: Hi team,
My customer want to use PSEMTHR24EVM-081 and TPS23881EVM-083.
Are there any recommended power supply units for using these?
Best regards,
Hi Ken,
Thanks for reaching out.
1 x TPS23881 has 8 channels, and a 4-paris port (> 30W) needs 2 channels for TPS23881. In your case if you want to output 8 x (>30W) ports, you will need 2 x TPS23881 chips. If it is <=30W per port, you can use 1 x…
Hi Jimmy,
It turns out to be a HW issue on our EVM. The pull up resistors on the I2C bus are not strong enough. After changing the pull up resistors (R11,R12,R33 and R34) on TPS23881EVM-083, the frequency is around ~400KHz. We will fix this in our…
Hi Cooper,
For the FW SRAM can you try instead downloading from link below? Yes you will need TI information to get access to this. Thanks!

Hi Jamie,
1. If you are looking at the TPS23881EVM-008, this pairs with the MSP5969 launchpad and the TI.com reference code on the TI.com reference page. If you're looking at the TPS23881EVM-083 or FirmPSE reference design TIDA-050026, then it pairs…
