DC Switching Voltage Regulators

LM2576-5.0WU-TR Description

The LM2576-5.0WU-TR is a fixed-output 5V, 3A buck (step-down) switching voltage regulator from Microchip Technology, designed for high-efficiency power conversion. Housed in a TO-263-5 (D2PAK) surface-mount package, it operates over a wide 4V to 40V input range, making it suitable for industrial, automotive, and consumer applications. With a 52kHz switching frequency, it balances efficiency and noise performance while minimizing external component count. The device is RoHS3 compliant, REACH unaffected, and rated for MSL 3 (168 hours) moisture sensitivity, ensuring reliability in harsh environments.

LM2576-5.0WU-TR Features

• Fixed 5V Output: Precision-regulated output eliminates the need for adjustable feedback components.
• High Current Capacity: Delivers 3A continuous current with thermal shutdown and current-limiting protection.
• Wide Input Range (4V–40V): Supports diverse power sources, including unregulated AC/DC adapters and batteries.
• 52kHz Switching Frequency: Optimizes efficiency (up to 88%) while reducing inductor/capacitor size.
• Non-Synchronous Buck Topology: Simplifies design with minimal external parts (diode, inductor, capacitors).
• Robust Packaging: TO-263-5 offers superior thermal performance for high-power applications.
• Compliance: Meets ROHS3, REACH, and EAR99/ECCN standards for global deployment.
