The LTM8078 is 40V_IN, dual 1.4A/single 2.8A step-down Silent Switcher μModule^® regulator. The Silent Switcher architecture minimizes EMI while delivering high efficiency at frequencies up to 3MHz. Included in the package are the controllers, power switches, inductors, and support components. Operating over a wide input voltage range, the LTM8078 supports output voltages from 0.8V to 10V, and a switching frequency range of 300kHz to 3MHz, each set by a single resistor. Only the bulk input and output filter capacitors are needed to finish the design. The LTM8078 product video is available on website.

LTM8078#3PP is an AEC-Q104 qualified automotive grade μModule regulator. The production is compliant to Analog Devices automotive assemble flow. All components integrated in the package are AEC-Q100 or AEC-Q200 qualified.

The LTM8078 is packaged in a compact (6.25mm × 6.25mm × 2.22mm) over-molded Ball Grid Array (BGA) package suitable for automated assembly by standard surface mount equipment. The LTM8078 is available with SnPb (BGA) or RoHS compliant.
