In the datasgeet of MPM540304 there is that the maximum output voltage is VIN*Dmax if Vin<7V. how much is Dmax?
thank you.

Hi Fabio,
The data sheet minimum off time will govern the max duty cycle. Given a fixed Fsw (default is 800kHz), the duty cycle is calculated by DCmax = (1- Fsw*Toff_min) . In this case the Toff_min = 133ns, and with Fsw=800kz, so the DCmax = 89.4%. If you choose a different Fsw you can use that in the calculation.
Regards,
