Texas Instruments recommends a 2-layer or 4-layer PCB with a solid ground plane and thermal vias to the bottom layer to dissipate heat efficiently. A minimum of 2 oz copper thickness is recommended for the top layer.
To ensure reliable operation at high temperatures, it is essential to follow the recommended thermal design guidelines, including proper heat sinking, thermal interface material, and airflow. Additionally, derating the output current and voltage can help reduce thermal stress.
The maximum allowed voltage on the enable pin is 6V, which is the absolute maximum rating. However, it is recommended to keep the enable voltage between 2.5V and 5.5V for reliable operation.
Yes, the LMR38010FSDDAR is qualified for automotive and high-reliability applications. It meets the AEC-Q100 standard for automotive applications and is suitable for use in harsh environments.
Output voltage instability or oscillations can be caused by inadequate decoupling, poor PCB layout, or insufficient output capacitance. Check the PCB layout, decoupling capacitors, and output capacitance to ensure they meet the recommended specifications. Additionally, verify that the input voltage is within the recommended range.
