High-density, 36V, 0.8V-to-16V output, dual 3A output power module

The TPSM6440xx is a highly integrated 36V input capable, DC/DC design that combines power MOSFETs, a shielded inductor, and passives in an enhanced HotRod QFN package. The device supports either dual output or high current single output using an interleaved, stackable, current-mode control architecture for easy loop compensation, fast transient response, excellent load and line regulation, and accurate current sharing with an output clock supporting up to 6 phases for currents up to 18A. The module has VIN and VOUT pins located at the corners of the package for optimized input and output capacitor placement. A large thermal pad beneath the module enable a simple layout and easy handling in manufacturing.

TPSM6440xx with ZEN 2 switcher technology is designed for minimal EMI. The device comes with Dual-random spread spectrum (DRSS) and integrated high frequency bypass capacitors in a symmetric package and the HotRod™ QFN package to lower switch node ringing and radiated noise. With an output voltage from 1V to 16V, the TPSM6440xx is designed to quickly and easily implement a low-EMI design in a small PCB footprint. The VCC and Bootstrap capacitor are integrated as well lowering the total external components needed to as few as six. The module can be configured for constant switching frequency over the full load current range (FPWM), or variable frequency (PFM) for higher light load efficiency. The switching frequency can be synchronized between 200kHz and 2.2MHz to avoid noise sensitive frequency bands.
