Product Details
The LTM8074 is a 40VIN, 1.2A continuous, 1.75A peak, step-down µModule® (power module) regulator. The Silent Switcher architecture minimizes EMI while delivering high efficiency at frequencies up to 2.2MHz. 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 LTM8074 supports an output voltage range of 0.8V to 12V 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 LTM8074 is packaged in a thermally enhanced, compact over-molded ball grid array (BGA) package suitable for automated assembly by standard surface mount equipment. The LTM8074 is RoHS compliant.
