TRACOPOWER Switching Regulator, Through Hole, -9V dc Output Voltage, -12 → -32V dc Input Voltage, -1A Output

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.
