The LTM8063 is a 40VIN, 2A continuous, 2.5A peak, stepdown 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 3.2V to 40V, the LTM8063 supports an output voltage range of 0.8V to 15V and a switching frequency range of 200kHz to 2.2MHz, 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 LTM8063 is packaged in a thermally enhanced, compact over-molded ball grid array (BGA) package suitable for automated assembly by standard surface mount equipment. The LTM8063 is RoHS compliant.

Evaluation Kits (1)
Demonstration circuit 2494A is a 40V, 2A step-down μModule® regulator featuring the LTM8063. The demo board is designed for 5V output from a 6.5V to 40V input. The wide input range allows a variety of input sources, such as automotive batteries and industrial supplies. The user adjustable features of the LTM8063 such as output voltage, switching frequency, soft-start, and power good can be changed on DC2494A simply by modifying the appropriate resistors and/or capacitors.
