The LTM®4703 is a complete 12A step-down Silent Switcher 3 μModule®(micromodule) regulator in a tiny 6.25mm × 6.25mm × 5.07mm ball grid array (BGA) package.The package includes the switching controller, the power MOSFETs, an inductor, and support components. Operating over an input voltage range of 3V to 16V, the LTM4703 supports an output range of 0.3V to 6V. 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 LTM4703 employs Silent Switcher 3 architecture with internal hot loop bypass capacitors to achieve both low electromagnetic interference (EMI) and high efficiency. Also, the LTM4703 has an ultralow noise architecture to obtain exceptional low-frequency (<100kHz) output noise. These low EMI and low noise features make the LTM4703 ideal for high current and noise-sensitive applications, which benefit from the high efficiency of a synchronous switching regulator.The LTM4703 is available with a RoHS-compliant terminal finish.APPLICATIONSTelecom, Networking, and Industrial EquipmentRF Power Supplies: PLLs, VCOs, Mixers, LNAs, PAsLow Noise InstrumentationHigh Speed/High Precision Data ConvertersMedical Equipment
