| Pin Number | Pin Name | Description |
|---|---|---|
| 1 | VIN | Supply Voltage Input Pin. XL1509 operates from a 4.5V to 40V DC voltage. Bypass Vin to GND with a suitably large capacitor to eliminate noise on the input. |
| 2 | OUTPUT | Power Switch Output Pin (SW). Output is the switch node that supplies power to the output. |
| 5~8 | GND | Ground Pin. Care must be taken in layout. This pin should be placed outside of the Schottky Diode to output capacitor ground path to prevent switching current spikes from inducing voltage noise into XL1509. |
| 3 | FEEDBACK | Feedback Pin (FB). Through an external resistor divider network, Feedback senses the output voltage and regulates it. The feedback threshold voltage is 1.23V. |
| 4 | ON/OFF | Enable Pin. Drive ON/OFF pin low to turn on the device, drive it high to turn it off. Floating is default low. |
