Hello Sir/Madam,

 I am intending to use LM5101A as the gate driver for load side PMOS switch drive of a boost converter.

 Boost Max output : 12V-16.5V

HI input gets the PWM signal (0-3.3V). I want the HO signal level shifted to drive the PMOS gate (0-16.5V). The bootstrap cap is connected between HS and HB. Could you please let me know in case i need to connect VDD pin to 16.5V supply  and HS pin to ground?

I have attached the schematic for reference.

Thanks

Sujan
