3-Watt DC-DC with 2:1 Input and -40°C to +85°C Operating Range

Traco Power has announced the release of their TRN 3 family of isolated and fully-regulated dc-dc converter modules that cover a wide range of low power applications where space is limited. The TRN 3 series feature wide 2:1 input ranges, a full load -40 to +65°C operating temperature range and are available in compact SIP or SMD packages (suffix SM).

The TRN 3 family consists of 32 standard models offering input ranges of 4.5- to 13.2-Vdc, 9- to 18-Vdc, 18- to 36Vdc, and 36- to 72-Vdc; output voltages of 3.3-, 5-, 12-, 15-, 24-, ±5-, ±12,- and ±15-Vdc; and SIP or SMD packages (suffix SM).

These 3W dc-dc converters feature tight regulation (0.2% Line / 1% Load max) with no minimum load required; 1,600 Vdc I/O Isolation; efficiency ranging from 75% to 84%; a full load operating temperature range of -40 to +65°C (up to +85°C with derating); short-circuit protection; and MTBF of 4,400,000h per MIL-HDBK-217F at 25°C.

Units are potted in a non-conductive plastic case and measure 0.47 x 0.30 x 0.43" (SIP) or 0.47 x 0.44 x 0.31 (SMD). Units are manufactured to IEC 60950-1 standards, qualified to MIL-STD-810F Thermal Shock & Vibration standards, are Reach / RoHS compliant and supported with a 3-year warranty.

Products are in stock and available through the Traco Power global distribution network with manufacturing lead times of 9-11 weeks.
