Product Details

Traco 1A Step-Down Switching Regulator TSR-1SM Series

The Tracopower TSR-1SM series of step-down switching regulators have a high efficiency up to 96%, which allows full load operation up to +65°C ambient temperature without the need of any heat transmission layer. The TSR-1SM switching regulators provide other significant features over linear regulators, i.e. better output voltage accuracy (±2 %) and lower standby current of 1 A. The high efficiency and low standby power consumption makes these regulators an ideal solution for many battery powered applications.
