The current of vin differs between 25 ° C and 10 ° C.
What are the possibilities?

hi, Seisou-san,
thank you for update .I will check with my team and give you a feedback later. Thank you.

Hi Seisou-san,
Please check that the DC/DC regulator is stable (look at the SW voltage waveform or take a load transient response). Please complete the LM25145 quickstart calculator and check stability (crossover frequency should be 10-15% of Fsw and phase margin > 50 degrees). Make sure to enterthe derated value for ceramic output capacitance as a function of applied voltage).
Regards,
Tim
