BTW68-1200RG datasheet by STMicroelectronics

BTW68-1200RG Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the BTW68-1200RG?
  A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the high-frequency traces short and away from the power plane. Use a common mode choke or a ferrite bead to filter the power supply.
• How do I ensure the BTW68-1200RG is properly biased for optimal performance?
  The BTW68-1200RG requires a bias voltage of 12V to 15V. Ensure the bias voltage is stable and filtered to prevent noise and oscillations. Use a voltage regulator or a low-dropout regulator to regulate the bias voltage.
• What is the maximum power handling capability of the BTW68-1200RG?
  The BTW68-1200RG can handle up to 1200W of peak power. However, the actual power handling capability depends on the application, PCB layout, and thermal management. Ensure proper heat sinking and thermal management to prevent overheating.
• How do I protect the BTW68-1200RG from overvoltage and overcurrent?
  Use a voltage clamp or a zener diode to protect the device from overvoltage. Implement overcurrent protection using a current sense resistor and a comparator or a dedicated overcurrent protection IC.
• What is the recommended operating frequency range for the BTW68-1200RG?
  The BTW68-1200RG is designed to operate from 100 kHz to 400 kHz. However, the optimal operating frequency range depends on the specific application and the transformer design.
