3 Board Layout
through
illustrate the board layout for the TPS7A74EVM-068 PCB.
The TPS7A74EVM-068 dissipates power, which may cause some components to experience an increase in
temperature. The TPS7A74 LDO and pulsed resistors R12, R13, R14, R15, and R16 are most at risk of
raising the junction temperature during normal operation. The LDO may become hot to the touch during normal
operation, see the thermal impedance discussion in the TPS7A74 data sheet.
