RGW80TK65DGVC11 - ROHM Semiconductor

RGW80TK65DGVC11 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  ROHM recommends a thermal pad size of 2.5mm x 2.5mm with a minimum of 10 thermal vias (0.3mm diameter) to ensure optimal heat dissipation. Additionally, a solid copper plane on the bottom layer can help to further reduce thermal resistance.
• How do I ensure stable operation during power-up and power-down sequences?
  To ensure stable operation, ROHM recommends a soft-start circuit to limit inrush current during power-up. For power-down, a gradual voltage reduction can help prevent voltage spikes and ensure a clean shutdown.
• What are the recommended input and output capacitors for this device?
  ROHM recommends using X7R or X5R ceramic capacitors with a minimum capacitance of 10uF for the input and output. The capacitor's ESR (Equivalent Series Resistance) should be less than 100mΩ to ensure stable operation.
• How do I protect the device from overvoltage and undervoltage conditions?
  ROHM recommends using a voltage supervisor or a voltage detector to monitor the input voltage and prevent operation outside of the recommended voltage range. Additionally, a TVS (Transient Voltage Suppressor) can be used to protect the device from voltage spikes and surges.
• What is the recommended operating temperature range for this device?
  The RGW80TK65DGVC11 is rated for operation from -40°C to 150°C (TJ). However, ROHM recommends derating the device's power dissipation to ensure reliable operation over the entire temperature range.
