Conducted emission requirements can be met by adding standard filter ponents. Included in the package are the switching controller, power switches, inductor, filters and all support ponents. Operating over an input voltage range of 3.6V to 36V, the LTM8031 supports an output voltage range of 0.8V to 10V, and a switching frequency range of 200k Hz 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 (2.82mm) enables utilization of unused space on the bottom of PC boards for high density point of load regulation. The LTM8031 is packaged in a thermally enhanced, pact (9mm ×15mm) and low profile (2.82mm) overmolded land grid array (LGA) package suitable for automated assembly by standard surface mount equipment. The LTM8031 is Ro HS pliant. L, LT, LTC, LTM, µModule, Burst Mode, Linear Technology and the Linear logo are registered trademarks of Linear Technology Corporation.
