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 vias to connect the input and output capacitors to the ground plane.
To ensure stability, follow the recommended component values and PCB layout, and make sure to decouple the input and output pins properly. Additionally, consider adding a small capacitor (e.g., 10nF) in parallel with the output capacitor to improve stability.
While the datasheet specifies a maximum input voltage of 6V, it's recommended to limit the input voltage to 5.5V to ensure reliable operation and to prevent damage to the device.
The LMR36506RF3RPER is rated for operation up to 125°C, but it's recommended to derate the output current and voltage at higher temperatures to ensure reliable operation. Consult the datasheet for more information on thermal derating.
Start by verifying the input voltage, output voltage, and output current. Check for proper decoupling, PCB layout, and component values. Use an oscilloscope to check for oscillations or noise on the output. Consult the datasheet and application notes for more troubleshooting tips.
