The TracoPower TSRN 1-2465 is a Non-isolated (POL) DC/DC Converter from the TSRN-1 Series. This step-down switching regulator is a drop-in replacement for inefficient 78xx linear regulators.
A high efficiency up to 95% 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 TSRN 1-2465 provides other significant features over linear regulators, i.e. better output accuracy (±2%), lower standby current of 2mA and no requirement of external capacitors.
It is suitable for both positive and negative output circuits. The high efficiency and low standby power consumption makes this regulator an ideal solution for energy sensitive applications.
