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 package
Input voltage range up to 42 VDC
Built in filter capacitors
No heat-sink required
Adjustable output voltage
Low 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 755-3457
Excellent line and load regulation
Over-temperature and short circuit protection
Remote On/Off input
Moisture sensitivity level (MSL) 1

Note

MTBF: MIL-HDBK-217F @ +25°C
Derating: 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 required
Load regulation is shown at 0-100 %, for 10-90% the load regulation would be 0.3 %
