TPSM33615: Recommended switching frequency

Kei Kuwahara
Expert 7325 points
Part Number: TPSM33615

Hello team,

My customer is trying to design system with 1MHz fixed frequency version of this device (TPSM33615FRDNR), because they want FPWM mode.

Customer design is 24Vin -> 12Vout / 0.4A.
However, on the datasheet, the recommeded SW frequency is 1600kHz when used in 24Vin -> 12Vout.

Can they use 1MHz version for this configuration?

Best Regards,
Kei Kuwahara
