[TPS65253] Low Power Mode

Other Parts Discussed in Thread: TPS65253

Hi Team!

I had a question regarding the TPS65253. I understand that the low power mode needs to be actively engaged. My question is this:

What would be the consequences of always using the TPS65253 in low power mode even at heavy loads?

Thank you for your support!

hI Ben.

If the low power pin put-in GND, always works low power mode.

Thank you for your answer, YG.

I just wanted to follow up with some comments in the event that someone else has the same questions. It is recommended not to use the pulse skipping mode if the load exceeds 150 mA. This will cause the device to operate less efficiently and also have a considerable amount of ripple.

Thanks!

The device will become unstable if attempting to load greater than 100mA while in low power mode
