TRACO POWER has announced the new TSR 2 series of step-down switching regulators that are drop-in replacement for inefficient LMxx linear regulators. A high efficiency up to 96% allows full load operation up to +67°C ambient temperature (full-load) without any heat-sink or forced cooling.

The TSR 2 switching regulators provide significant features over linear regulators including better output accuracy (±2 %), lower standby current of 1mA and no requirement of external capacitors.

These regulators come in an ultra-compact SIP Package that measures only 0.55x0.30x0.40”. The product family consists of 14 models with output voltages ranging 1.2 ~ 15VDC.

All models are tightly regulated and operate with 1% load variation from 0~100%, overload protection, and extreme reliability exceeding 13 Million hours per MIL-HDBK-217F. The DC input ranges from 3.0 to 36.0VDC depending on the model which make them ideal for point of load regulators for industrial and battery powered applications.

All models are Reach and RoHS compliant and supported by a three year warranty.
