Board Layout

Figure 3-1 through Figure 3-6 illustrate the board layout for the TPS7A14EVM-058 PCB.

Figure 3-7 through Figure 3-12 illustrate the board layout for the TPS7A14EVM-095 PCB

The TPS7A14EVM-058 and TPS7A14EVM-095 dissipate power, which can cause some components to experience an increase in temperature. The TPS7A14 LDO, LMG1020YFFR gate driver, and pulsed resistors R2, R3, R4, R5, and R6 are most at risk of raising to a high junction temperature during normal operation.
