Analog Devices Inc. LTM4702 8A Step-Down Silent Switcher® Regulator

Analog Devices LTM4702 8A Step-Down Silent Switcher® μModule® Regulator that comes in a tiny 6.25mm × 6.25mm × 5.07mm BGA package, which includes the switching controller, an inductor, a power MOSFET, and support components. Operating over an input voltage range of 3V to 16V, the LTM4702 series supports an output range of 0.3V to 5.7V. A single resistor sets the output voltage, providing unity gain operation over the output range. This results in virtually constant output noise independent of the output voltage. Only bulk input and output capacitors are needed to finish the design. The Analog Devices LTM4702 series employs Silent Switcher architecture with internal hot loop bypass capacitors to achieve low EMI and high efficiency. These μModule regulators modules offer ultra-low noise architecture to obtain exceptional low-frequency (<100kHz) output noise and are ideal for noise-sensitive and high-current applications.
