Driver pin to gate of external PFET. Output power stage ground connection. Oscillator frequency programming capacitor Logic ground. Feedback voltage input. Logic supply voltage. Soft start and fault timing capacitor. Driver supply voltage.
Adding the BST Supply Diode and Capacitor A signal diode, such as a lN4148, works well for D2 in most applications, although a low-leakage Schottky diode provides slightly improved efficiency. Do not use large power diodes, such as the lN4001 0r 1N5817. Exercise caution in the selection of Schottky diodes, since some types exhibit high reverse leakage at high operating tem- peratures. Bypass BST to LX using a 0.1 pF capacitor.
