LMR38020FDDAR Frequently Asked Questions (FAQ)
-
A 2-layer or 4-layer PCB with a solid ground plane and thermal vias is recommended. Keep the thermal pads connected to the ground plane to improve heat dissipation.
-
Monitor the input voltage, output voltage, and output current to ensure they are within the recommended operating conditions specified in the datasheet. Use proper thermal management and PCB design to prevent overheating.
-
A low-ESR ceramic capacitor (e.g., X5R or X7R) with a value of 10uF to 22uF is recommended for input decoupling. Place the capacitor close to the VIN pin to minimize noise and improve stability.
-
Use a shielded enclosure, keep the switching node (SW) away from sensitive nodes, and use a common-mode choke or ferrite bead on the output to reduce EMI. Follow proper PCB layout and grounding techniques to minimize radiation.
-
A low-ESR ceramic capacitor (e.g., X5R or X7R) with a value of 10uF to 22uF is recommended for output filtering. Place the capacitor close to the VOUT pin to minimize noise and improve stability.
