TMH2415D - Traco Power

TMH2415D Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  Traco Power recommends a PCB layout with a large copper area connected to the module's thermal pad to ensure good heat dissipation. A minimum of 1 oz copper thickness is recommended, and the copper area should be connected to a solid ground plane to reduce thermal resistance.
• How do I ensure reliable start-up of the module in high-temperature environments?
  To ensure reliable start-up in high-temperature environments, Traco Power recommends using a soft-start circuit or a ramp-up circuit to limit the inrush current during start-up. This can be achieved using an external circuit or by using a module with a built-in soft-start feature.
• What is the maximum capacitance I can use on the output of the module?
  The maximum capacitance on the output of the TMH2415D is limited by the module's stability and transient response. Traco Power recommends using a maximum capacitance of 10uF to 22uF, depending on the specific application and output voltage. Exceeding this limit may cause oscillations or instability in the output voltage.
• Can I use the TMH2415D in a redundant or parallel configuration?
  Yes, the TMH2415D can be used in a redundant or parallel configuration to achieve higher power or redundancy. However, Traco Power recommends using a dedicated ORing diode or a redundancy module to ensure proper operation and to prevent back-feeding of power between modules.
• What is the recommended input fuse rating for the TMH2415D?
  Traco Power recommends using a fuse with a rating of 2A to 5A, depending on the specific application and input voltage. The fuse should be able to handle the maximum input current of the module, including inrush current during start-up.
