Pin Configuration
XL4015E1 Pinout
Package: TO-263-5 (TO263-5L)
| Pin Number | Pin Name | Type | Description |
|---|---|---|---|
| 1 | GND | P | Ground |
| 2 | FB | I | Feedback |
| 3 | SW | O | Switch |
| 4 | VC | I | Voltage Compensation |
| 5 | VIN | P | Input Voltage |
| Tab | SW | O | Switch (Metal Tab, connected to Pin 3) |
Notes
- The metal tab is electrically connected to Pin 3 (SW) and should be soldered to the same net for improved thermal performance.
- Pin 4 (VC) is typically connected to ground through a capacitor for compensation purposes.
- Pin 2 (FB) is the feedback input for output voltage regulation.
