TSR 1-48240WI

Non-Isolated DC/DC Converter (POL) • 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 • Pin compatible with LMxx linear regulators (SIP-3) • Operating temperature range -40 to +80°C • • • Low standby current • 3-year product warranty Excellent line/load regulation Protection against short circuit, overvoltage and overtemperature TSR 1WI Series The TSR 1WI is a non-isolated POL converter series with an ultra wide 8:1 input voltage range which comes in a standard SIP-3 package. Covering the majority of standard bus- and battery voltages this POL converter is a versatile solution for many applications in distributed power systems where different input voltages have to be handled. Being able to use the same converter in many different situations effectively reduces the bill of material (BOM) of a given application. A high efficiency of up to 93% allows for an operating temperature range of -40 to +80°C (up to 50°C without derating) and makes them excellent drop-in replacements for less efficient LMxx linear regulators. With 1.0 A max. output current and standard features such as low standby current, precise regulation and protection against short circuit, overvoltage and overload the TSR 1WI is suitable for many battery and distributed power applications. on demand (on demand (backorder with MOQ, - Optional models with angular pins (see outline dimensions) non stocking item) non stocking item) Input Specifications (It is recommended to use an external input filter, please refer to application note: www.tracopower.com/overview/tsr1wi) VDC model: 1'000 mA (slow blow) 1'250 mA (slow blow) 1'600 mA (slow blow) 1'250 mA (slow blow) (The need of an external fuse has to be assessed in the final application.)
