The LTM4702 is a complete 8A step-down Silent Switcher®3 μModule®regulator in a tiny 6.25mm × 6.25mm × 5.07mm BGA package. Included in the package are the switching controller, the power MOSFETs, an inductor, and support components. Operating over an input voltage range of 3V to 16V, the LTM4702 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 and resulting in virtually constant output noise independent of the output voltage. Only bulk input and output capacitors are needed to finish the design.The LTM4702 employs Silent Switcher 3 architecture with internal hot loop bypass capacitors to achieve both low EMI and high efficiency. Also, the LTM4702 has an ultralow noise architecture to obtain exceptional low-frequency (<100kHz) output noise. These low EMI and low noise features make the LTM4702 ideal for high current and noise-sensitive applications, which benefit from the high efficiency of a synchronous switching regulator.The LTM4702 is available with SnPb or RoHS-compliant terminal finish.ApplicationsTelecom, Networking, and Industrial EquipmentRF Power Supplies: PLLs, VCOs, Mixers, LNAs, PAsLow Noise InstrumentationHigh Speed/High Precision Data Converters
