TRACO POWER TSR2-2425

DC/DC Converter TSR 2 Series, 2 A ◆ Ultra compact SIP package 0.55 x 0.30 x 0.40 inch ◆ Up to 96 % efficiency – No heat-sink required ◆ Pin compatible with LMxx linear regulators ◆ Built in filter capacitors ◆ Operating temperature range -40°C to +85°C ◆ Excellent line / load regulation ◆ Short circuit protection ◆ 3-year product warranty The new TSR 2 series step-down switching regulators are drop-in replacement for inefficient LMxx linear regulators. A high efficiency up to 96 % allows full load operation up to +67°C ambient temperature without the need of any heat-sink or forced cooling. The TSR 2 switching regulators provide other significant features over linear regulators, 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.
