TPS57040-Q1: Measurement data of 5V start/stop voltage

Jeffrey Chung1

Part Number: TPS57040-Q1

Hi Team,

I'd like to ask you about the measurement data of 5V start/stop voltage. there is no detailed measurement data on under 5mA output current in datasheet like the graph below. Please share it with me if you have the data.

Hi Jeffery,

The estimated Start/Stop voltage for 5mA load is about 5.5 based on Fig 27.

Hi Andy,

I already checked the start/stop voltage at 5mA output current point as you post on previous thread. What I want to know is the measurement data of under 5mA load such as 1mA, 2mA, 3mA, and 4mA. Please check it again and let me know.

Hi Jeffrey,

Sorry we don't have the data as this was quite old part, Do you or customer have TPS57040 EVM to test it? Pls support customer to apply one and test it.

Hi Andy,

There is no TPS57040 EVM on TI site. I will try to request my customer to test it even though it is very hard to test.
