  • Page 3: Introduction

    TPS7A14EVM-058 contains one TPS7A14 LDO voltage regulator in the DSBGA package and the TPS7A14EVM-095 contains one TPS7A14 LDO voltage regulator in WSON package . An optional load transient circuit is also included to assist the user with high-speed load transient testing. An input current loop is included that allows fast measurements of the input current.

    The slots were sized to fit most current probes, such as the LeCroy AP015 or CP031 current probes. Figure 2-2. TPS7A14EVM-058 With Current Probes Attached The user has two options for providing a DC load on the output of the TPS7A14. J10 can be used to place a DC load that flows through the current sense path on the output of the LDO.

  • Page 6: Optional Load Transient Circuit Operation

    2.4 Optional Load Transient Circuit Operation The TPS7A14EVM-058 and TPS7A14EVM-095 evaluation modules contains an optional high-performance load transient circuit to allow efficient testing of the TPS7A14 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 TPS7A14 LDO to match the expected operating conditions.

  • Page 8: Board Layout

    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.
