TracoPower Non-isolated (POL) DC/DC Converter, TSRN-1 Series

TracoPower Brand: TracoPower

A range of TracoPower Non-isolated (POL) DC/DC Converters from the TSRN-1 Series. These straight pin step-down switching regulators are 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 switching regulators provide other significant features over linear regulators, i.e. better output accuracy (±2%), lower standby current of 2mA and no requirement of external capacitors. They are suitable for positive and negative output circuits.

The high efficiency and low standby power consumption make these regulators an ideal solution for energy sensitive applications.
