Part Number: TPSM365R3

Hi Team,

I want to use the TPSM365R3 with a fixed output of 3.3V.

For the lab testing I would like to have the ability to change the switching frequency (by changing the resistor value) but maintaining the fixed output.

From the picture above i can see that this configuration is possible:

TPSM365R3V3FRDNR.

But I don't see that option in the following table:

I just want to make sure that it is possible to have fixed output voltage with adjustable switching frequency.

Many Thanks!

hi, Ohad,

Please refer to DS page 22, 9.3.6 External CLK SYNC (with MODE/SYNC). But the RT function is not , this pin is internal trimmed.

notice the pin description here,

Hi Elena,
Not sure that i understand your answer.

Can we have a part variant with fixed output voltage and trimmed as RT? we don't need the sync option nor external clock

Best regards.

hi, Ohad,

We only provide the deice trim option as listed. For your device if need change frequency ,only way is use external clock, not RT. We may not open a new project unless a big volume or target marketing/customer.
