Fremont Micro Devices Ltd FT440AA is a highly efficient buck switching regulator IC offering an adjustable positive output voltage from 0.6V up to 5.5V. This component is designed for step-down conversion and supports a maximum output current of 600mA. Featuring a 1.5MHz switching frequency, the FT440AA minimizes external inductor size and improves transient response. Its integrated synchronous rectifier further enhances efficiency, reducing power loss. The device operates from a 2.5V to 5.5V input voltage range and is housed in a compact SOT-23-5 package, suitable for surface mounting. Typical applications include portable electronics, battery-powered devices, and power management in consumer electronics. The FT440AA is supplied in Tape & Reel packaging and operates within an ambient temperature range of -40°C to 85°C.
