TracoPower TSR Series 1W DC-DC Converters - Single Output

TracoPower Brand: TracoPower

The TracoPower 1W DC-DC Converters are step-down switching regulators that act as drop-in replacements for inefficient 78xx linear regulators. A high efficiency up to 96% allows full load operation up to +60°C ambient temperature without the need of any heat-sink or forced cooling.

The TSR-1 switching regulator provides other significant features over linear regulators, i.e. better output accuracy (±2 %), lower standby current of 2mA and no requirement of external capacitors. The high efficiency and low standby power consumption make this regulator an ideal solution for many battery powered applications.
