Analog Devices' LTM8065 is a 40 VIN, 3.5 A peak, 2.5 A continuous step-down µModule (power module) regulator. Included in the package are the switching controller, power switches, inductor, and all support components. Operating over an input voltage range of 3.4 V to 40 V, the LTM8065 supports an output voltage range of 0.97 V to 18 V and a switching frequency range of 200 kHz to 3 MHz, each set by a single resistor. Only the 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. The LTM8065 is packaged in a thermally enhanced, compact over-molded ball grid array (BGA) package suitable for automated assembly by standard surface mount equipment. The LTM8065 is RoHS compliant.
