EVAL-LTM4732-AZ

EVAL-LTM4732-AZ is a 16V, 4A ultralow noise Silent Switcher 3 μModule regulator in a tiny 6.25mm × 4mm × 1.92mm ball grid array (BGA) package. The package includes the switching controller, the power MOSFETs, an inductor, and the supporting components. Operating over an input voltage range of 3V to 16V, the LTM4732 supports an output range of 0.3V to 6V. A single resistor sets the output voltage, enabling unity-gain operation over the output range and resulting in virtually constant output noise independent of the output voltage. Only the bulk input and output capacitors are required to complete the design. Suitable for telecom, networking, and industrial equipment, RF power supplies: PLLs, VCOs, mixers, LNAs, PAs, low-noise instrumentation, high speed/high precision data converters applications.
