## 2. Design Considerations
### Common Design Pitfalls and Solutions
Gate Drive Issues
*Pitfall*: Inadequate gate drive current leading to slow switching and excessive switching losses
*Solution*: Implement gate drivers capable of delivering 2A peak current with proper decoupling
Thermal Management
*Pitfall*: Underestimating thermal requirements causing premature failure
*Solution*: Use thermal simulation tools and provide adequate heatsinking based on application power dissipation
PCB Layout Problems
*Pitfall*: Excessive parasitic inductance in high-current paths causing voltage spikes
*Solution*: Minimize loop areas and use proper decoupling capacitor placement
### Compatibility Issues with Other Components
Gate Drivers
- Compatible with most industry-standard gate driver ICs (IR21xx series, UCC2751x series)
- Requires attention to gate drive voltage levels (recommended VGS = 10-15V)
- May exhibit compatibility issues with slow-rise-time drivers
Control ICs
- Works well with modern PWM controllers from TI, Analog Devices, and Infineon
- May require additional snubber circuits when used with certain resonant controllers
Passive Components
- Requires low-ESR input/output capacitors for optimal performance
- Gate resistors should be selected based on switching frequency requirements
### PCB Layout Recommendations
Power Path Layout
- Use wide copper pours for drain and source connections (minimum 2oz copper recommended)
- Keep high-current traces as short as possible to minimize parasitic resistance
- Implement multiple vias for thermal management and current sharing
Gate Drive Circuit
- Place gate driver IC close to the MOSFET (within 10mm ideal)
- Use separate ground returns for gate drive and
