A good PCB layout for the TPS92390RHBR involves placing the input capacitors close to the VIN pin, using a solid ground plane, and keeping the high-current paths short and wide. It's also recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
When choosing an inductor for the TPS92390RHBR, consider the inductor's saturation current, DC resistance, and core material. A good starting point is to select an inductor with a saturation current rating of at least 1.5 times the maximum output current, and a DC resistance of less than 100 mΩ.
The TPS92390RHBR is rated for operation from -40°C to 125°C, but the maximum ambient temperature range depends on the specific application and the device's power dissipation. In general, it's recommended to keep the ambient temperature below 85°C for reliable operation.
The TPS92390RHBR has a built-in overcurrent protection feature that can be enabled by connecting the OCSET pin to a resistor divider network. The resistor values should be chosen to set the overcurrent threshold to the desired value, typically 1.5 to 2 times the maximum output current.
Yes, the TPS92390RHBR is qualified for automotive and high-reliability applications. It meets the AEC-Q100 standard for automotive grade devices and is suitable for use in harsh environments. However, it's essential to follow proper design and manufacturing guidelines to ensure the device meets the required reliability standards.
