LMZ31710: Switching Frequency Setting

Sam Ting

Part Number: LMZ31710

Dear Sirs,

For 1V output, could we set the switching frequency higher rather than 250KHz which is the recommended setting in datasheet Table.2? Thanks!

Best regards,

Sam Ting

Yes, the LMZ31710 can operate at other frequencies for 1V output. The switching frequency range will depend on Vin. See table 7 of the datasheet.

Hi Arrigo,

Thanks for your answer!
Is it the limitation of min-on-time when operating at lower duty cycle?

Best regards,

Yes, minimum on-time is the limitation.
