LTM80xx Step-Down µModule® Regulators

Analog Devices Inc. LTM80xx are 40VIN, 3.5A (continuous) Step-Down Silent Switcher μModule® (power module) Regulators. Included in the package are the switching controller, power switches, inductor, and all support components. The components operate over an input voltage range of 3.4V to 40V. The LTM8003 supports an output voltage range of 0.97V to 18V. The LTM8053 from Analog Devices supports an output voltage range of 0.97V to 15V. Both devices have a switching frequency range of 200kHz to 3MHz, each set by a single resistor. Only the input and output filter capacitors are needed to finish the design.
