TRACOPOWER

Traco 1A SMD Step Down Switching Regulator - TSRN-1SM Series TSRN-1SM series step-down switching regulators with a wide input voltage range of up to 42 Vdc and a high efficiency of up to 95% which allows full load operation without the need for a heatsink or forced air cooling. These TSRN-1SM series 1A step-down switching regulators are suitable for positive and negative output circuits (see table for additional data) and have trim input for output voltage adjustment. A low standby power consumption and high efficiency makes these switching regulators ideal for use in energy saving applications. Compact SMD packageInput voltage range up to 42 VDCBuilt in filter capacitorsNo heat-sink requiredAdjustable output voltageLow standby current: Positive output circuit: 1.5 mA for stock number 755-3447, 4 mA for all other models. Negative output circuit: -3.3 / -5.5 V models: 3 mA, -9.0 / -12 V models: 7 mA and 10 mA for stock number 755-3457Excellent line and load regulationOver-temperature and short circuit protectionRemote On/Off inputMoisture sensitivity level (MSL) 1 Additional Data RS Stock Number Manufacturer Part Number Input Voltage Range Output Voltage Max Output Current Efficiency Typ @ Vin min Efficiency Typ @ Vin max Positive Output Circuit             755-3447 TSRN 1-2433SM 4.6 → 42 Vdc 3.3 Vdc (1.5 → 5.5 Vdc trim range) 1.0 A 87 % 80 % 755-3441 TSRN 1-2450SM 6.5 → 42 Vdc 5.0 Vdc (2.5 → 8.0 Vdc trim range) 1.0 A 91.5 % 83 % 755-3450 TSRN 1-2490SM 10.5 → 42 Vdc 9.0 Vdc (4.5 → 12.6 Vdc trim range) 1.0 A 94.5 % 89 % 755-3453 TSRN 1-24120SM 13.5 → 42 Vdc 12 Vdc (4.5 → 13.5 Vdc trim range) 1.0 A 95 % 91 % 755-3457 TSRN 1-24150SM 16.5 → 42 Vdc 15 Vdc (4.5 → 15.5 Vdc trim range) 1.0 A 95.5 % 92.5 % Negative Output Circuit             755-3447 TSRN 1-2433SM 4.6 → 32 Vdc -3.3 Vdc (-1.5 → -5.5 Vdc trim range) 0.6 A 74% 77% 755-3441 TSRN 1-2450SM 4.6 → 31 Vdc -5.0 Vdc (-2.5 → -8.0 Vdc trim range) 0.4 A 80% 78% 755-3450 TSRN 1-2490SM 7 → 27 Vdc -9 Vdc (-4.5 → -12.6 Vdc trim range) 0.3 A 85% 82% 755-3453 TSRN 1-24120SM 7 → 24 Vdc -12 Vdc (-4.5 → -13.5 Vdc trim range) 0.3 A 84% 86% 755-3457 TSRN 1-24150SM 7 → 21 Vdc -15 Vdc (-4.5 → -15.5 Vdc trim range) 0.2 A 85% 84% Note MTBF: MIL-HDBK-217F @ +25°CDerating: 1.7 %/K above +55°C (positive circuit)Derating: 2.5 %/K above +65°C (negative circuit)For input voltage higher than 36 Vdc an input capacitor 22 μF/ 50 V is requiredLoad regulation is shown at 0-100 %, for 10-90% the load regulation would be 0.3 % Switching Regulators ; Input Voltage 4.6 → 31 V dc, 6.5 → 42 V dc; Output Voltage ±5V dc; Number of Outputs 1; Output Current 1 A, 400 mA; Mounting Type Surface Mount; Package SMD; Minimum Temperature -40°C; Maximum Temperature +85°C; Efficiency 78 %, 83 %; MTBF 6000000h; Load Regulation ±0.6%; Line Regulation ±0.2%; Ripple And Noise 50mV Pk-Pk; Length 15.2mm; Depth 7.2mm; Weight 1.7kg; Width 9.3mm;
