Hi, team.

Do you have a graph of TPS63010 overcurrent threshold and input voltage dependency?

On the evaluation board, nearly 3A input current flows at 2 Vin.

I want a graph like TPS63024 Fig.8.

Hello Hirotsugu-san,

The average input current should not exceed the average switch current limit.
Did you rework the EVM before doing this test? What is the output current you are drawing at 2V? Please check if the device gets hot.

Best regards,
Brigitte

Hi, Briritte,

Is there a dependence on the input voltage?

The output voltage is 4.7 V and the output current is 0.92 A.

(The input voltage was 2 V, the input current was 3.2 A.)

Hello Hirotsugu-san,

There is for sure a slight dependency on the input voltage, but not such a lot. Please check if the IC gets hot when there is no load connected. Please as well check the input current with no load.

Best regards,
Brigitte

Hello Hirotsugu-san,

I haven’t heard back so I’m assuming you were able to resolve your issue. If not, just post a reply below (or create a new thread if the thread has locked due to time-out.

Best regards,
Brigitte
