- Problem : Inadequate current delivery causing slow MOSFET switching and excessive switching losses
- Solution : Calculate required gate charge and ensure ADP3610's 2A peak current meets application requirements
Pitfall 2: Ground Bounce Issues
- Problem : High di/dt causing voltage spikes in ground reference
- Solution : Implement star grounding, use separate power and signal grounds, add local decoupling capacitors
Pitfall 3: Shoot-Through Current
- Problem : Simultaneous conduction in complementary MOSFET pairs
- Solution : Implement adequate dead time in control logic, typically 50-100 ns depending on application
Pitfall 4: EMI/RFI Generation
- Problem : High-frequency switching creating electromagnetic interference
- Solution : Use proper shielding, implement snubber circuits, follow high-frequency layout practices
