TRACO POWER TSR1-2425SM

DC/DC Converters TSR-1SM Series, 1 A Features ◆ SMD-package ◆ Up to 96 % efficiency ◆ No thermal layer required ◆ Built in filter capacitors ◆ Operation temp. range –40°C to +85°C ◆ Short circuit protection The new TSR-1SM series models of step-down switching regulators have a high ef- ◆ Wide input operating range ficiency up to 96 % which allows full load operation up to +65°C ambient tempera- ◆ Excellent line / load regulation ture without the need of any heat transmission layer. ◆ Low standby current Excellent output voltage accuracy (±2%) and low standby current (~1 µA) are fea- tures that distinguish these switching regulators from linear regulators. ◆ 3-year product warranty Models Order code Input voltage range Output voltage Output current Efficiency typ. max. @ Vin min. @ Vin max.
