(1)
The maximum output voltage is limited by the overvoltage protection threshold and not be the maximum switch voltage rating.
(2)
The GD signal is latched low when the main boost converter output VS is within regulation. The GD signal is reset when the input
voltage or enable of the boost converter is cycled low.
