TPC8128 - Toshiba

TPC8128 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the TPC8128 to minimize EMI?
  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 edges of the board. Use a common mode choke and a ferrite bead to filter the input power.
• How do I ensure the TPC8128 is properly cooled?
  Use a heat sink with a thermal resistance of 10°C/W or lower. Apply a thin layer of thermal interface material (TIM) between the heat sink and the TPC8128. Ensure good airflow around the heat sink.
• What is the maximum allowed voltage on the VIN pin?
  The maximum allowed voltage on the VIN pin is 28V. Exceeding this voltage may damage the device.
• How do I protect the TPC8128 from overcurrent?
  Use an external current sense resistor and a fuse or a PTC (Positive Temperature Coefficient) thermistor to limit the current. The TPC8128 also has an internal overcurrent protection (OCP) feature that can be enabled.
• Can I use the TPC8128 in a high-temperature environment?
  The TPC8128 is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. Ensure proper cooling and derate the device's power handling accordingly.
