TSR 1 Series 1 A POL DC/DC Converters

TRACO Power’s non-isolated step-down regulators feature an increased output accuracy of ±2% and a low standby current of 2 mA

Image of TRACO Power's TSR 1 Series 1 A POL DC/DC ConvertersTRACO Power’s TSR 1 series step-down switching regulators are a drop-in replacement for inefficient 78xx linear regulators. This series has high efficiency of up to 96%, allowing for full load operation up to +60°C ambient temperature without needing a heat-sink or forced cooling.

The TSR 1 switching regulators feature an increased output accuracy (±2%), a low standby current of 2 mA, and no external capacitors requirements. The high efficiency and low standby power consumption make these regulators an ideal solution for a wide range of battery-powered applications.

For new applications requiring a non-isolated 1 amp solution, see the cost-efficient TSR 1E series.
