TRACOPOWER TMR 3-4811WIR DC/DC Converter, 3 W, 5 V, 600 mA, SIL-8, 4:1 Input, 1600 VDC Isolation

Powering sensitive electronics in industrial and automotive environments often requires a stable, isolated DC voltage from a fluctuating input rail. The TRACOPOWER TMR 3-4811WIR is a 3 W DC/DC converter that delivers a regulated 5 VDC output from a wide 9–36 VDC input, making it ideal for battery-powered systems, distributed power architectures, and noise-sensitive circuits.

Who is it for

Engineers and integrators working on industrial control, transportation, or telecom equipment who need a compact, board-mounted converter with galvanic isolation and a wide input range. Its SIL-8 package fits standard through-hole layouts, and remote on/off control simplifies power sequencing.

Tips

Ensure adequate PCB copper area for heat dissipation, especially at full load and high ambient temperatures. Use low-ESR capacitors close to the input and output pins to minimize ripple and improve transient response. The remote on/off pin can be driven by a logic signal or left floating for always-on operation.
