2-Amp Step-Down Switching Regulators Operate to 67 Degrees C

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 0.55 x 0.30 x 0.40".

The product family consists of 14 models with output voltages ranging 1.2- to 15-Vdc. All models are tightly regulated and operate with 1% load variation from 0 to 100%, overload protection, and extreme reliability exceeding 13 million hours per MIL-HDBK-217F.

The input ranges from 3.0- to 36.0-Vdc depending on the model which make them suited for point-of-load regulators for industrial and battery powered applications. All models are Reach and RoHS compliant and supported by a 3-year warranty.
