Description
XL4015E1 Step-Down DC/DC Converter IC
XLSEMI XL4015E1 is a fixed-frequency PWM buck (step-down) regulator in a five-lead TO-263-5L package.
- Input voltage: 8–36V operating range
- Adjustable output: 1.25–32V
- Output current capability: up to 5A, subject to operating conditions and thermal design
- Switching frequency: 180kHz
- Minimum dropout: 0.3V (datasheet specification)
- Package: TO-263-5L surface mount
The 5A figure is a chip capability, not a guarantee for every circuit or thermal setup. This is the regulator IC only, not a complete DC-DC converter module; external components and a suitable PCB layout are required. See the datasheet and the XLSEMI datasheet for application circuits, pinout and limits.
