The XL4015 is a 5 A, 180 kHz fixed-frequency step-down (buck) DC-DC converter with 8–36 V input and up to 96% efficiency.
Product Overview
The XL4015 is a 180 kHz PWM buck converter capable of driving a 5 A load with high efficiency, low ripple, and excellent line/load regulation. An internal compensation block and built-in power MOSFET minimize external components, while over-current, thermal, and short-circuit protection ensure robust operation in the TO-263-5 package.
Newfly supplies verified, RoHS-compliant XL4015-class converter ICs with cross-reference and BOM-matching support for production sourcing.
