The Analog Devices Inc. LTC3128IFE is a synchronous buck-boost switching regulator designed for high-efficiency power conversion. This adjustable output device provides a positive output voltage from 1.8V up to 5.5V, capable of delivering up to 3A of continuous current. Operating with an input voltage range of 1.73V to 5.5V, the LTC3128IFE utilizes a 1.2MHz switching frequency, which enables the use of compact external components. Its advanced buck-boost topology ensures seamless transition between step-up and step-down modes, minimizing output voltage ripple and improving transient response. The device is housed in a 24-TSSOP (0.173", 4.40mm width) package with an exposed pad for enhanced thermal performance. Typical applications include battery-powered systems, point-of-load converters, and portable electronics where efficient voltage regulation is critical.
