PFC2723ER-421K03B-00 - TDK

PFC2723ER-421K03B-00 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the PFC2723ER-421K03B-00?
  TDK recommends a 4-layer PCB with a solid ground plane and a separate power plane for the input and output. The component should be placed near the input capacitors, and the output capacitors should be placed close to the load. A thermal via under the component is also recommended for heat dissipation.
• How do I ensure the reliability of the PFC2723ER-421K03B-00 in high-temperature applications?
  To ensure reliability, it's essential to follow the recommended derating curves for temperature and output power. Additionally, ensure good thermal design, including a heat sink and thermal interface material, and consider using a thermistor or thermal sensor to monitor the temperature.
• What is the maximum allowed voltage stress on the PFC2723ER-421K03B-00 during startup or fault conditions?
  The maximum allowed voltage stress on the PFC2723ER-421K03B-00 is 450V, as specified in the datasheet. However, it's recommended to limit the voltage stress to 400V or less to ensure reliable operation and prevent damage to the component.
• Can I use the PFC2723ER-421K03B-00 in a design with a high dv/dt?
  Yes, the PFC2723ER-421K03B-00 is designed to handle high dv/dt applications. However, it's essential to follow the recommended layout and design guidelines to minimize parasitic inductance and ensure reliable operation.
• What is the recommended method for soldering the PFC2723ER-421K03B-00?
  TDK recommends using a reflow soldering process with a peak temperature of 260°C (500°F) and a dwell time of 30 seconds. Hand soldering is not recommended due to the component's high power density and thermal sensitivity.
