The LTM4707 is a complete 16A step-down Silent Switcher 3 power μModule® (power micromodule) 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 the supported components. Operating over an input voltage range of 3V to 16V, the LTM4707 supports an output range of 0.3V to 6V. A single resistor sets the output voltage, providing unity-gain operation over the output range, resulting in virtually constant-output noise independent of output voltage. Only bulk input and output capacitors are needed to finish the design.
The LTM4707 employs Silent Switcher 3 architecture with internal hot loop bypass capacitors to achieve both low electromagnetic interference (EMI) and high efficiency. The LTM4707 has an ultralow noise architecture to obtain exceptional low frequency (<100kHz) output noise. These low EMI and low noise features make the LTM4707 ideal for high current and noise-sensitive applications that benefit from the high efficiency of a synchronous switching regulator. The LTM4707 is available with a RoHS-compliant terminal finish.
