INN3675C-H601-TL - Power Integrations

INN3675C-H601-TL Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  A 2-layer PCB with a solid ground plane on the bottom layer and a thermal relief pattern on the top layer is recommended. This helps to dissipate heat efficiently and reduce thermal resistance.
• How do I ensure reliable start-up and shutdown of the INN3675C-H601-TL?
  Ensure that the input voltage rises and falls slowly (typically 10-20 ms) to prevent inrush currents and ensure reliable start-up and shutdown. Also, add a soft-start circuit to limit the inrush current.
• What is the maximum allowed voltage on the BYPASS pin?
  The maximum allowed voltage on the BYPASS pin is 6.5V. Exceeding this voltage may damage the internal voltage regulator.
• How do I optimize the design for low standby power consumption?
  Use a low-ESR capacitor on the output, minimize the number of external components, and ensure that the input voltage is as low as possible while still meeting the required output voltage. Also, consider using a low-power mode or shutdown mode when the device is not in use.
• What is the recommended input capacitor type and value for the INN3675C-H601-TL?
  A low-ESR ceramic capacitor (e.g., X5R or X7R) with a value of 10-22 μF is recommended. This helps to filter out input voltage ripple and ensure stable operation.
