XL7015E1 0.8A 150KHz 80V Buck DC to DC Converter TO 252-5

XL7015E1 0.8A 150KHz 80V Buck DC to DC Converter TO 252-5

The XL7015E1 is a high-efficiency step-down (buck) DC-DC converter IC designed to provide a reliable, compact, and cost-effective solution for voltage regulation and power management in industrial, automotive, and communication applications.

Manufactured by XLSEMI, this converter integrates a high-voltage (up to 80V) switching MOSFET and operates at a fixed 150kHz frequency, ensuring efficient and stable conversion from higher DC input voltages to regulated lower DC outputs. It supports an output current up to 0.8A, making it ideal for powering logic circuits, microcontrollers, sensors, and other low-power devices directly from higher DC sources.

The XL7015E1 features thermal shutdown, over-current protection, and cycle-by-cycle current limiting for enhanced reliability. Its TO-252-5 (DPAK) package provides excellent heat dissipation and ease of PCB assembly for surface-mount designs.
