Analog Devices Inc. LTM8024 40VIN Silent Switcher µModule Regulator
Analog Devices Inc. LTM8024 Step-Down Silent Switcher µModule® Regulator is ideal for automotive battery regulation, power for portable products, distributed supply regulation, and industrial supplies. The 40VIN, dual 3.5A or single 7A step-down Silent Switcher architecture minimizes electromagnetic interference (EMI) while delivering high efficiency at frequencies up to 3MHz. LTM8024 supports output voltages from 0.8V to 8V, and a switching frequency range of 200kHz to 3MHz, each set by a single resistor. The LTM8024 contains current mode controllers, power switching elements, power inductors and a modest amount of input and output capacitance. The LTM8024 is a fixed frequency PWM regulator. The switching frequency is set by simply connecting the appropriate resistor value from the RT pin to GND.
