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.

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 %
