The TPS7H4010-SEP (Space Enhanced Plastic) evaluation module (EVM) with orderable part number
TPS7H4010EVM, is designed to help customers evaluate the performance of the TPS7H4010-SEP synchronous
step-down voltage converter. The EVM contains two independent buck converter circuits, each of which contains
the TPS7H4010-SEP which is in the 30-pin wettable flanks QFN (WQFN) package. The two circuits deliver very
accurate output voltages at 1.8 V and 3.3 V with up to 6 A current capacity with exceptional efficiency in a very
small solution size. The EVM provides multiple power connectors and test points, as well as mode setting and
enable input options, allowing for flexibility in testing.

Figure 5-1 through Figure 5-5 show the board layout for the TPS7H4010EVM. The EVM offers resistors, capacitors, and test points to configure the output voltage, precision enable pin, set frequency, and external clock synchronization. The 30-pin WQFN package offers an exposed thermal pad which must be soldered to the copper landing on the PCB for optimal thermal performance. -
