The LTC3809EDD#TRPBF is a high current, low noise, synchronous buck-boost DC-DC converter switching regulator from Analog Devices. It is capable of delivering up to 5A of continuous load current and is also capable of output voltages as low as 0.8V. Its low noise and high current design makes it ideal for applications requiring a small form factor and wide input voltage range, such as point-of-load applications. It features an integrated 1.25V reference and adjustable Soft-Start circuit, as well as built-in current limit protection. The device is housed in a 9-pin, leadless, plastic DFN package with a 0.5mm pitch, which allows for a much smaller total solution size than using a discrete solution. The LTC3809EDD#TRPBF also has a wide input voltage range from 3V to 20V, and is available in a -40°C to 85°C extended temperature range.
