DC Switching Voltage Regulators

MIC4576-3.3WU-TR Description

The MIC4576-3.3WU-TR is a high-performance, fixed-output 3.3V, 3A buck (step-down) DC switching voltage regulator from Microchip Technology. Designed for efficiency and reliability, it operates over a wide input voltage range of 4V to 36V, making it suitable for industrial, automotive, and embedded systems requiring stable power conversion. With a 200kHz switching frequency, it balances performance and noise reduction, while its non-synchronous rectifier topology ensures cost-effective power management. Packaged in a TO263-5 (D2PAK) surface-mount format and supplied in Tape & Reel (TR), it is optimized for automated assembly. The device is RoHS3 compliant and adheres to REACH environmental standards, ensuring global compatibility.
