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 1.25V. Connect a resistor divider to FB. |
|
4 |
EN |
Regulator On/Off Control Input. A high input at EN turns on the converter, and a 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. |
