Fremont Micro Devices Ltd FT441AA is a high-frequency synchronous buck switching regulator. This adjustable positive output device delivers up to 900mA with an output voltage range from 0.6V to 5.5V. Operating with a minimum input voltage of 2.5V and a maximum of 5.5V, the FT441AA features a switching frequency of 1.5MHz, enabling the use of smaller external components. The device is packaged in a SOT-23-5 (SC-74A, SOT-753) surface-mount configuration, supplied on tape and reel. Its efficient buck topology and synchronous rectification make it suitable for power management in portable electronics, industrial control systems, and automotive applications where space and power efficiency are critical.
