TRACO POWER TSRN1-0525SM

TRACO POWER DC/DC Converters TSRN1-SM SERIES 1 Watt Non-Isolated / POL Power Supply TSRN-1SM Series, 1 A Switching Regulator Measures: 0.60 x 0.37 x 0.29” Features ◆ Compact SMD package ◆ Suitable for positive & negative output circuit ◆ Adjustable output voltage ◆ Wide input up to 42 VDC ◆ Remote On/Off input ◆ Built in filter capacitors ◆ Operation temp. range –40°C to +85°C ◆ No heat-sink required ◆ Over-temperature protection ◆ Short circuit protection The new TSRN-1SM series are step-down non–isolated switching regulators in com- pact SMD package. They are an ideal solution to replace inefficient linear regula- ◆ Excellent line / load regulation tors. The high efficiency up to 95 % allows full load operation up to +55°C (+85°C ◆ Low standby current with derating) ambient temperature without the need of forced aircooling. ◆ Moisture sensitivity level (MSL) 1 The TSRN-1SN switching regulators provide other significant features over linear regulators, i.e. better output accuracy (±2 %), lower standby current of ~4 mA and ◆ Qualified for leadfree reflow solder no requirement of external capacitors. They are suitable for positive or negative process output circuits and offer a trim input for output voltage adjustment. The high ef- ◆ 3-year product warranty ficiency, low standby power consumption and remote On/Off function make these regulators an ideal solution for energy sensitive applications.
