Part Number: TPS62056
Other Parts Discussed in Thread: TPS62065

Dear Specialists,

My customer is considering TPS62065 and has a question.

I would be grateful if you could advise.

As a condition for entering Power-Save Mode

There was a description in the data sheet as follows.

" The current is 100 mA at low input voltages and up to 200 mA with maximum input voltage. "

At this time, the input voltage is 5V and output voltage is 3.3V.

In this condition, which is the threshold current 100mA or 200mA.

I suspect it is "low input voltages" and it the threshold current is 100mA to "Power-Save Mode".

Is this correct?

I appreciate your great help in advance.

Best regards,

Shinichi,

The skip threshold will vary between 100mA and 200mA based on the input voltage. Thus, as 5V is a little less than a 1/3 of the way between 3V and 10V, you can better approximate the transition into power save mode to be around 130mA.

Sincerely,

-Mattt
