***TEXAS: The TPS54478 device is a full featured 6-V, 4-A, synchronous step down current mode converter with two integrated MOSFETs.

***ASI: The TPS54478 enables small designs by integrating the MOSFETs, implementing current mode control to reduce external component count, reducing inductor size by enabling up to 2-MHz switching frequency, and minimizing the IC footprint with a small 3-mm × 3-mm thermally enhanced WQFN package.

***AS INSRUMENT: The TPS54478 provides accurate regulation for a variety of loads with an accurate ±1% voltage reference (VREF) over temperature. Efficiency is maximized through the integrated 30-mΩ MOSFETs and 525-µA typical supply current. Using the enable pin, shutdown supply current is reduced to 2.5 µA by entering a shutdown mode.

***as Instruments Inc.: Undervoltage lockout is internally set at 2.6 V, but can be increased by programming the threshold with a resistor network on the enable pin. The output voltage start-up ramp is controlled by the soft-start pin. An open-drain power-good signal indicates the output is within 93% to 107% of its nominal voltage.

***AS INSTUMENTS: Cycle-by-cycle current limit, hiccup overcurrent protection, and thermal shutdown protect the device during an overcurrent condition.
