Block Diagram PIN DESCRIPTION SO- 8 1 DFN- 10 1 Symbol BST Description Upper MOSFET Floating Bootstrap Supply. A capacitor connected between BST and SW pins holds this bootstrap voltage for the high- side MOSFET as it is switched. The remended capacitor value is between 100 n F and 1.0 m F. An external diode is required with the NCP3418B. Logic- Level Input. This pin has primary control of...
