Product Details

The LTM®8071 is a 60VIN, 5A (continuous) step-down Silent Switcher 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 3.6V to 60V, the LTM8071 supports an output voltage range of 0.97V 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 LTM8071 is packaged in a compact over-molded ball grid array (BGA) package suitable for automated assembly by standard surface mount equipment. The LTM8071 is available with SnPb (BGA) or RoHS compliant terminal finish.
