TSR 1-4833WI TRACO Power

Non-Isolated DC/DC Converter (POL) TSR 1WI Series, 1 A Ultra wide 8:1 input voltage range: 9-72 VDC Covers a majority of standard bus- and battery voltages Up to 93% efficiency - No heatsink required The TSR 1WI is a non-isolated POL converter series with an ultra wide 8:1 input Pin compatible with LMxx linear voltage range which comes in a standard SIP-3 package. Covering the majority regulators (SIP-3) of standard bus- and battery voltages this POL converter is a versatile solution Operating temperature range for many applications in distributed power systems where different input volt- -40 to +80C ages have to be handled. Being able to use the same converter in many differ- ent situations effectively reduces the bill of material (BOM) of a given applica- Low standby current tion. A high efficiency of up to 93% allows for an operating temperature range Excellent line/load regulation of -40 to +80C (up to 50C without derating) and makes them excellent drop-in replacements for less efficient LMxx linear regulators. With 1.0 A max. Protection against short circuit, output current and standard features such as low standby current, precise reg- overvoltage and overtemperature ulation and protection against short circuit, overvoltage and overload the TSR 3-year product warranty 1WI is suitable for many battery and distributed power applications.
