• Using transient voltage suppressors (TVS) for surge protection.
• Verifying load conditions to prevent excessive current draw.

Electromagnetic Interference (EMI)

High-frequency switching can introduce noise. To minimize EMI:

• Follow proper grounding techniques and use shielded traces where necessary.
• Place decoupling capacitors close to the power pins.
• Optimize switching frequencies to balance efficiency and noise.

Component Selection and Layout

Incorrect passive component choices can lead to instability. Recommendations:

• Use high-quality, low-ESR capacitors for filtering.
• Ensure proper trace widths to handle current without excessive resistance.
• Follow the manufacturer’s recommended layout guidelines for optimal performance.
