Let me ask about TPS61040 and TPS61041.

Is the difference between TPS61040 and TPS61041 only an output current value?

If there are other differences, please let me know.

RDSon is also different as well as switch peak current limit.

Hi,John-san

Thank you for the reply.

I would sometimes like to hear one more.

Is a difference between TPS61041 and TPS61040 in addition to the contents indicated to the data sheet?

(When transposed to TPS61040 from TPS61041, the noise occurred in the picture outputted.)

Hi.

If there is a difference considered to originate in an image noise in the portion which is not indicated to a data sheet Please let me know.

Best Regards,

The only difference between the devices is the Rdson and current limit, as previously stated. Since the device works by ramping up the inductor current to the current limit value during each switching cycle, these differences might affect output voltage ripple, etc. which might impact the performance in the system.
