PIN DESCRIPTION PIN NAME FUNCTION
1 SW Power Switch Output. SW is the drain of the internal MOSFET switch. Connect the power inductor and output rectifier to SW. SW can swing between GND and 28V. 2 GND Ground Pin 3 FB Feedback Input. The FB voltage is 0.6V. Connect a resistor divider to FB. Regulator On/Of Control Input. A high input at EN turns on the converter, and a 4 EN low input turns it off. When not used, connect EN to the input supply for automatic startup. 5 IN Input Supply Pin. Must be locally bypassed. 6 NC NC
