Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general high-frequency PCB design guidelines, such as using a solid ground plane, minimizing trace lengths, and using bypass capacitors to reduce noise and ringing.
The LM5035ASQX/NOPB has a thermal pad on the bottom of the package, which should be connected to a thermal plane on the PCB. Additionally, ensure good airflow around the device, and consider using a heat sink or thermal interface material if the device will be operating at high temperatures or high power levels.
The maximum allowed voltage on the EN pin is VCC + 0.3V, but it's recommended to keep it below VCC to ensure proper operation. Exceeding this voltage may cause damage to the device.
Yes, the LM5035ASQX/NOPB is qualified for automotive and high-reliability applications, but it's essential to follow Texas Instruments' recommended design and testing guidelines to ensure the device meets the required specifications and standards.
Start by verifying the PCB layout and component values match the recommended design. Check for proper power supply decoupling, and ensure the input and output capacitors are properly sized. Use an oscilloscope to measure the output voltage and current, and consult the datasheet and application notes for troubleshooting guidelines.
