Part Number: TPS25730

Hi team,

Customer is evaluating TPS25730 using our EVM.

They set Minimum Voltage Configuration to 9V by ADC1, and Maximum Voltage Configuration to 20V by ADC2. So they think that this would only get 9V~20V voltage pass through TPS25730.

When 5V get input, there will be no voltage pass through TPS25730. However the EVM test shows that 5V could still pass through TPS25730 to PPHV.

Could you help comments why this happen and if we could block the voltage out of the setting range?

Thanks and Best Regards,

Will

This is expected behavior that is going to be changed for the next revision of the TPS25730, which we are currently working on.

Right now, the part boots into AlwaysEnableSink mode, which closes the power path upon boot (until configuration is loaded). For the next revision, the part will boot into SafeMode, which will keep the power path open until configuration is loaded.

Kind regards,

Conner Gillette

Hi Conner,

For the reversion, does it mean we will release a new part number or it's just a PCN?

Thanks and Best regards,
