Demonstration Circuit For LTM8032 Ultralow EMI, 36V, 2A DC-DC Umodule Regulator

is a demonstration circuit to evaluate the performance of the LTM8032 DC/DC µModule regulator. The LTM8032 is an electromagnetic compatible EMC 36V, 2A DC/DC µModule buck converter designed to meet the radiated emissions requirements of EN55022. Conducted emission requirements can be met by adding standard filter components. Included in the package are the switching controller, power switches, inductor, filters and all support components. Operating over an input voltage range of 3.6V to 36V, the LTM8032 supports an output voltage range of 0.8V to 10V, and a switching frequency range of 200KHz to 2.4MHz, each set by a single resistor. Only the bulk input and output filter capacitors are needed to finish the design. The low profile package enables utilization of unused space on the bottom of PC boards for high density point of load regulation.
