Analog Devices Inc. LTM8078 40VIN Silent Switcher® µModule® Regulator
Analog Devices Inc. LTM8078 Silent Switcher® μModule® Regulator is a 40VIN, dual 1.4A/single 2.8A step-down device. The Silent Switcher architecture minimizes EMI and delivers high efficiency at frequencies up to 3MHz. The controllers, power switches, inductors, and support components are included. The Analog Devices LTM8078 operates over a wide input voltage range and supports output voltages from 0.8V to 10V. The switching frequency range operates from 300kHz to 3MHz, each set by a single resistor. Only the bulk input and output filter capacitors are needed to finish the design.
