Product Details

The LTM8083 is a 36VIN, Buck-Boost μModule® Regulator. Included in the package are the switching controller, power switches, inductor, and support components. All that is needed to complete the design is resistors for setting the output voltage and operating frequency, and input and output capacitors. Operating over an input voltage range from 3V to 36V, the LTM8083 can regulate output voltages between 1V and 36V with seamless low-noise transitions between operation regions, as well as controlling both input and output average currents through external sense resistors.

The low profile package enables utilization of unused space on the bottom of PC boards for high density point of load regulation. The LTM8083 is packaged in thermally enhanced, compact over-molded Ball Grid Array (BGA) packages suitable for automated assembly by standard surface mount equipment. The LTM8083 is RoHS compliant.
