XL4015 Pin Configuration
XL4015 Pinout
Package: TO263-5L (PCB Module)
| Pin Number | Pin Name | Type | Description |
|---|---|---|---|
| 1 | GND | P | 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 XL4015. |
| 2 | FB | I | Feedback Pin (FB). Through an external resistor divider network, FB senses the output voltage and regulates it. The feedback threshold voltage is 1.25V. |
| 3 | SW | O | Power Switch Output Pin (SW). SW is the switch node that supplies power to the output. |
| 4 | VC | P | Internal Voltage Regulator Bypass Capacitor Pin (VC). The VC pin connects a 1µF capacitor to VIN. |
| 5 | VIN | P | Supply Voltage Input Pin. XL4015 operates from 8V to 36V DC voltage. Bypass VIN to GND with a suitably large capacitor to eliminate noise on the input. |
| — | Metal Tab SW | — | Metal tab connected to SW (switch node). |
Notes
- Pin numbers verified against the TO263-5L package diagram (top view).
- The metal tab on the back of the package is electrically connected to the SW pin.
- VIN operating range: 8V to 36V DC.
- FB feedback threshold: 1.25V.
- VC requires a 1µF bypass capacitor to VIN.
