DC/DC converter TracoPower TMA 1515S, 1 W, 15 V output, 65 mA, SIL-7 package

TracoPower TMA 1515S is a compact DC/DC converter that provides 1 W of isolated power with a fixed 15 V output and a maximum output current of 65 mA in a SIL-7 package. Intended for board-level integration, this module delivers galvanic isolation between input and output while converting low-power rails to a regulated 15 V supply. Its small footprint and industry-oriented design make it suitable for embedded control systems and industrial electronics where space and electrical isolation are required.

Advantages

The converter offers galvanic isolation to protect sensitive circuits and reduce noise coupling between domains. With regulated output voltage and short-circuit tolerant behavior typical for TracoPower designs, it supports stable operation under varying input conditions. The SIL-7 packaging provides a compact, through-hole mount option for secure board attachment and straightforward integration into existing assemblies.

Suitable for

• Board-level power isolation in industrial control systems
• Embedded electronics requiring a small, regulated 15 V rail
• Signal processing modules and sensor interfaces needing galvanic isolation
• Low-power communication and measurement equipment

Key specifications

• Output power: 1 W
• Output voltage: fixed 15 V
• Maximum output current: 65 mA
• Package type: SIL-7 through-hole module
• Function: isolated DC/DC voltage conversion for board-level use

How to use

Install the module on the PCB using the SIL-7 through-hole pins, ensuring correct orientation and recommended clearance for isolation. Apply the specified input voltage within the device's rated range and observe polarity. Provide adequate decoupling on input and output according to system requirements. Verify the output under load conditions up to the rated 65 mA and monitor temperature during initial operation to confirm thermal compatibility with the enclosure and surrounding components.

Usage recommendations

For reliable performance, place the converter away from high-power dissipating components and allow airflow or heatsinking if ambient temperatures are elevated. Use appropriate input filtering and surge protection on the supply line when deploying in industrial environments. Ensure creepage and clearance distances on the PCB meet safety and isolation requirements for the intended application.
