LTM4732 Step-Down μModule® Regulators

Analog Devices LTM4732 Step-Down μModule^® Regulators are complete 4A step-down Silent Switcher^® 3 power μModule (micromodule) regulators 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.
