Compact 10W railway approved DC/DC converter with wide 4:1 input voltage range

The TMR 10WIR series is a family of ruggedised 10 Watt DC/DC converters for highest reliability in harsh environments. The converters have a wide 4:1 input range and increased resistance against electromagnetic interference, shock/vibration, and thermal shock, and come in a SIP-8 metal package.

The innovative design provides high efficiencies up to 89% and thus enable an operating temperature range from –40 up to +75°C without derating. The approvals according to standards EN 50155 and EN 61373 qualify them for railway and transportation systems. Additional qualification for the fire behaviour of components according to EN 45545-2 and the safety approval according IEC/- EN62368-1, UL62368-1 support a potential compliance test of the application. Built-in features like input under-voltage-lockout, short circuit protection, and remote on/off make this series suitable for almost any application demands and thus facilitate the design-in process.
