Texas Instruments recommends a 2-layer PCB with a solid ground plane on the bottom layer and a thermal relief pattern on the top layer to ensure optimal thermal performance. A minimum of 2 oz copper thickness is recommended for the PCB.
To ensure reliable operation at high temperatures, it's essential to follow the recommended operating conditions, including derating the output current and voltage according to the temperature derating curve provided in the datasheet. Additionally, ensure good thermal design and heat sinking to keep the junction temperature below 150°C.
The maximum allowed voltage on the input pins is 6.5V, which is the absolute maximum rating. However, for reliable operation, it's recommended to keep the input voltage within the recommended operating range of 3.5V to 5.5V.
The TPPM0111DWPR has built-in ESD protection, but it's still recommended to follow proper ESD handling procedures during assembly and testing. Use an ESD wrist strap or mat, and ensure that the device is handled in a static-safe environment.
The recommended input capacitance for the TPPM0111DWPR is 10nF to 100nF, depending on the specific application requirements. A larger input capacitance can help improve noise filtering and stability, but may also increase the startup time.
