LTM4702EY#PBF

LTM®4702 is a complete 8A step-down ultra low noise Silent Switcher® µModule® regulator. Included in the package are the switching controller, the power MOSFETs, an inductor, and support components. A single resistor sets the output voltage, providing unity gain operation over the output range and resulting in virtually constant output noise independent of the output voltage. Only bulk input and output capacitors are needed to finish the design. It employs Silent Switcher architecture with internal hot loop bypass capacitors to achieve both low EMI and high efficiency. Also, it has an ultralow noise architecture to obtain exceptional low-frequency output noise. Application includes telecom, networking, and industrial equipment, RF power supplies: PLLs, VCOs, Mixers, LNAs, PAs, low noise instrumentation, high speed/high precision data converters.
