RS Components, Ltd. 7553453P

Description
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 Input Voltage = 13.5 - 42 V dc, 7 - 24 V dc Output Voltage = ±12V dc Number of Outputs = 1 Output Current = 1 A, 300 mA Mounting Type = Surface Mount Package = SMD Minimum Temperature = -40°C Maximum Temperature = +85°C Efficiency = 86 %, 91 % MTBF = 6000000h Delivery on production packaging - Tube. This product is non-returnable.
