The Traco Power TSN 1 Series of step down switching regulators are a replacement for inefficient 79xx linear regulators. This series of DC/DC converters feature a high efficiency up to 96%, which allows full load operation up to +70°C (+85°C with derating) ambient temperature without the need of any heat sink or forced air cooling. The TSN 1 series of switching regulators also features over linear regulators, lower standby current and no requirement of external capacitors. The TSN 1 DC/DC converters are ideal in applications for energy sensitive applications. Non-isolated converter for negative output. Small size and low profile. Pin compatible with LM79xx linear regulators. No heatsink required. High efficiency up to 96%. Operation temperature range –40°C to +85°C. Protection against overload, short circuit and over-temperature. Fixed switching frequency. Wide input range up to -32 Vdc. Excellent line / load regulation. Low standby current ~ 2 mA. 3-year product warranty Input Voltage = -7.5 - -32V dc Output Voltage = -5V dc Number of Outputs = 1 Output Current = -1A Mounting Type = Through Hole Minimum Temperature = -40°C Maximum Temperature = +85°C Efficiency = 92% Load Regulation = 0.6% Line Regulation = 1%
