POL DC/DC converters with an ultra-wide input voltage range

The newly developed TSR-WI Series of non-isolated DC/DC converters TRACO push the limits of input voltage range up to 72VDC, which covers 99% of current and upcoming applications.
This is an archive article published 11/27/2019. Some information may no longer be up to date and in line with the current state. Please contact us in case of interest.

The TSR-WI line is a set of non-isolated POL (Point of Load) converters with an ultra-wide 8:1 input voltage range coming in standard SIP-3 packages.

Covering the majority of the 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.

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.

Converters of the TSR-WI line are suitable for many battery and distributed power applications.

For price, delivery and more information about TRACOPOWER products, please visit our webpage or contact us at sales@soselectronic.com

Main features:
  • Ultra-wide 8:1 input voltage range: 9-72 VDC
  • Covers a majority of the standard bus- and battery voltages
  • Up to 94% efficiency - no heatsink required
  • Pin compatible with LMxx linear regulators (SIP-3)
  • Operating temperature range -40 to +85°C
  • Low standby current
  • Excellent line/load regulation
  • Protection against short circuit, overvoltage and overtemperature
  • 3-year product warranty
