Traco Power - new 0.6 and 1A POL converters


Traco Power has introduced a new range of ultra wide 8:1 input POL converters to cover many standard bus- and battery voltages.

The TSR-WI line is a set of non-isolated POL converter series with an ultra wide 8:1 input voltage range which come in standard SIP-3 packages. Covering the majority of standard bus- and battery voltages this POL converter line 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 94% allows for an operating temperature range of -40 to +85°C and makes them excellent drop-in replacements for less efficient LMxx linear regulators. Available with 0.6 or 1A max. output current and standard features such as low standby current, precise regulation and protection against short circuit, overvoltage and overload the TSR-WI line is suitable for many battery and distributed power applications.
