The MIC4685WR is a high-efficiency 200kHz step-down (buck) switching regulator designed by Microchip Technology. It is capable of delivering 3A of continuous output current and offers an adjustable output voltage ranging from 1.235V to 28.2V. The regulator operates within a wide input voltage range of 4V to 30V, with a transient rating of 34V, making it suitable for applications with potential input voltage fluctuations.
Key features include over-current protection, frequency-foldback short-circuit protection, and thermal shutdown for enhanced safety. The device achieves over 85% efficiency, minimizing heat generation and often requiring only the PCB ground plane for heat sinking. It is internally compensated for fast transient response.
The MIC4685WR is housed in a low-profile 7-pin SPAK package, which offers a smaller footprint compared to TO-263 packages. This surface-mount package is suitable for various applications, including point-of-load power supplies and simple high-efficiency step-down conversions. The operating junction temperature range is -40°C to +125°C.
