The TPS82130 is a 3-A, synchronous, step-down module in a 2.8- × 3.0- × 1.53-mm package. The inductor and IC are included in the device. The TPS82140 and TPS82150 are pin-to-pin compatible power modules supporting lower output currents. See Table 1-1 for a summary of the PWR720 EVMs.

Table 1-3 shows the PWR720 EVM thermal data after considering the printed-circuit board (PCB) design of real applications. Compared to the JEDEC values listed in the data sheet, the PWR720 EVM design uses thicker copper on the 2 internal layers, has bigger planes connecting to the IC, and uses a thinner PCB. These improve the thermal performance. But the PCB is smaller than the standard JEDEC PCB, and this decreases the thermal performance. Overall, these differences improve the thermal performance and more closely match a real end application.
