MP6001 - input up to 120V

DC-DC Power Converters
1

We have an application which requires input between 20Vdc and 120Vdc. MP6001 almost is a perfect choice except that Vin works up to 100V and the absolute rating is 120V. What is the leakage current of Vin while off after startup? I am wondering if inserting a 10V zener in series may do the job.

Or any better solution?

Hello vincenttam,

The leakage current is:image.

Yes, the zener diode could work to drop the Vin in breakdown. Please size the zener correctly.

Thank you,
