WPR15100 - BUCK

Hello,

I would like to create a wireless power receiver with the component MWPR1516 and i'm working with the WPR1500 - Buck as an example. However, I have some questions about the schematic:

1 - How the Vrec protection work ? (on sheet 4/5)

When Vrec is higher than 20V (+Vgs threshold) , it enables the 2 Mos. But what are the consequences on Vrec ?

2 - What is the purpose of the Switch_En ? (on sheet 4/5)

Is it to discharge the capacitor when we turn the device off ?

Thank you for your help.

With best regards,

Olivier
