Pin Functional Description
DRAIN (D) Pin:
This pin is the power MOSFET drain connection. It provides
internal operating current for both start-up and steady-state
operation.
BYPASS/MULTI-FUNCTIONAL PROGRAMMABLE
(BP/M) Pin:
This pin has multiple functions:
1. It is the connection point for an external bypass capacitor for
2. It is a mode selection for the cable drop compensation for
FEEDBACK (FB) Pin:
During normal operation, switching of the power MOSFET is
controlled by this pin. This pin senses the AC voltage on the bias
winding. This control input regulates both the output voltage in
CV mode and output current in CC mode based on the flyback
voltage of the bias winding. The internal inductance correction
circuit uses the forward voltage on the bias winding to sense the
bulk capacitor voltage.
SOURCE (S) Pin:
This pin is internally connected to the output MOSFET source for
high voltage power and control circuit common returns.
