ABSTRACT Figure 1-1. TPS7B4255EVM-062 Evaluation Module This user's guide describes the operational use of the TPS7B4255EVM-062 evaluation module (EVM) as a reference design for engineering demonstration and evaluation of the TPS7B4255-Q1 low-dropout linear regulator (LDO). Included in this user's guide are setup and operating instructions, thermal and layout guidelines, a printed-circuit board (PCB) layout, a schematic diagram, and a bill of materials (BOM).
Failure to adhere to these steps or to not heed the safety requirements at each step may lead to shock, injury, and damage to the hardware. Texas Instruments is not responsible or liable in any way for shock, injury, or damage caused by negligence or failure to heed advice. If you are not trained in the proper safety of handling and testing power electronics please do not test this evaluation module.
TPS7B84-Q1 LDO after VIN is applied. Figure 3-1 illustrates the result of the TPS7B4255EVM-062 during turn-on. Jumper J14 has a shunt to connect EN of the TPS7B84-Q1 to VIN to enable the device for this turn-on plot. TPS7B4255EVM-062 Evaluation Module SLVUCA5 –...
Setup www.ti.com Figure 3-2. TPS7B4255EVM-062 With Current Probes Attached The user has two options for providing a DC load on the output of the TPS7B4255-Q1. J7 can be used to place a DC load that flows through the current sense path on the output of the LDO. Alternatively, the J4 (VOUT) and J10 (GND) banana connectors can be used for external measurements and loading;...
Setup 3.4 Optional Load Transient Circuit Operation The TPS7B4255EVM-062 evaluation module contains an optional high-performance load transient circuit to allow efficient testing of the TPS7B4255-Q1 LDO load transient performance. To use the optional load transient circuit, install the correct components in accordance with the application. Modify the input and output capacitance connected to the TPS7B4255-Q1 LDO to match the expected operating conditions.
TPS7B4255EVM-062 PCB. The TPS7B4255EVM-062 dissipates power, which may cause some components to experience an increase in temperature. The TPS7B4255-Q1 LDO and pulsed resistors R9, R10, R11, R12, and R13 are most at risk of raising the junction temperature during normal operation.
