The LTC3779 data sheet shows the Vin (Pin 34) Input Supply Operating Voltage Range from 4.5V to 150V. Does it have to be the same voltage as the Vin for High Current Top N-Channel MOSFETs?
If not, how low in can be for safe operation?

Hi John,
In my application, the Vin on the MOSFETs is +120V. I want to know if LTC3779 will work correctly with the Vin on the Pin 34 less then the voltage on the MOSFETs. I want to power LTC3779 (on Pin 34) from separate power supply +28V or less.
