TRACO POWER TSR1-2425

DC/DC Converters TRACO POWER TSR1 SERIES TSR-1 Series, 1 A 1 Amp DC Regulator Measures: 0.46 x 0.40 x 0.30” Features ◆ Up to 96 % efficiency – No heat-sink required ◆ Pin compatible with LMxx linear regulators ◆ SIP-package fits existing TO-220 footprint ◆ Built in filter capacitors ◆ Operation temp. range –40°C to +85°C ◆ Short circuit protection ◆ Wide input operating range ◆ Excellent line / load regulation ◆ Low standby current ◆ 3-year product warranty The new TSR-1 series step-down switching regulators are drop-in replacement 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 regulators provide other significant features over linear regu- lators, i.e. better output accuracy (±2 %), lower standby current of 2 mA and no requirement of external capacitors. The high efficiency and low standby power consumption makes these regulators an ideal solution for many battery powered applications.
