A 2-layer or 4-layer PCB with a thermal relief pattern and a solid ground plane is recommended. Ensure that the thermal pad is connected to a large copper area to dissipate heat efficiently.
Use a capacitor with an ESR of 10 ohms or less, and ensure that the capacitor is placed close to the IC. Additionally, add a 1-10nF ceramic capacitor in parallel to the output capacitor to filter high-frequency noise.
The maximum allowed voltage on the EN pin is 6V. Exceeding this voltage may damage the IC.
The BD69730FV-GE2 is rated for operation up to 105°C. However, the IC's performance and reliability may degrade at high temperatures. Ensure that the IC is properly heat-sinked and that the operating temperature is within the specified range.
Check the PCB layout for noise coupling, ensure that the input and output capacitors are properly decoupled, and verify that the feedback network is properly connected. Also, check for any signs of overheating or excessive current draw.
