Texas Instruments TPSM64404/TPSM64406 Dual Output Power Modules
Texas Instruments TPSM64404/TPSM64406 Dual Output Power Modules are a highly integrated 36V input capable, DC-DC design that combines a shielded inductor, power MOSFETs, and passives in an enhanced HotRod™ QFN package. The device supports dual or high current single output using an interleaved, stackable, current-mode control architecture for a fast transient response, easy loop compensation, excellent load and line regulation. It also includes accurate current sharing with an output clock supporting up to six phases for currents up to 18A. The module has VIN and VOUT pins at the package's corners for optimized output and input capacitor placement. A large thermal pad beneath the module enables easy handling and a simple layout in manufacturing.
With an output voltage from 1V to 16V, the Texas Instruments TPSM64404/TPSM64406 is designed to quickly and easily implement a low-EMI design in a small PCB footprint. The total design requires as few as six external components and eliminates the magnetics selection from the design process.
