A bootstrap capacitor is connected between the BOOST and SW pins. Signal and Power ground pin. Place the bottom resistor of the feedback network as close as possible to this pin for accurate regulation. Feedback pin. Connect FB to the external resistor divider to set output voltage. Enable control input. Logic high enables operation. Do not allow this pin to float or be greater than VIN + 0.3V. Input supply voltage. Connect a bypass capacitor to this pin. Output switch. Connects to the inductor, catch diode, and bootstrap capacitor. 3 4 5 6 FB EN VIN SW .national. Free Datasheet http://../ Absolute Maximum Ratings (Note 1) If Military/Aerospace...
