Traco Power TSRN 1-24120SM electric converter

The new TSRN 1SM series are step-down non–isolated switching regulators in compact SMD package. They are an ideal solution to replace inefficient linear regulators. The high efficiency up to 95% allows full load operation up to +55°C (+85°C with derating) ambient temperature without the need of forced air cooling.
The TSRN-1SM switching regulators provide other significant features over linear regulators, i.e. better output accuracy (±2%), lower standby current of ~4 mA and no requirement of external capacitors. They are suitable for positive or negative output circuits and offer a trim input for output voltage adjustment. The high efficiency, low standby power consumption and remote On/Off function make these regulators an ideal solution for energy sensitive applications.
