9- to 72-Vdc Input, 0.6A and 1A Non-Isolated DC-DC Converters

September 21, 2019 by Paul Shepard

The TSR-WI line from Traco Power is a set of non-isolated point-of-load (PoL) dc-dc 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 conversion 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 0.6A 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 linen is suitable for many battery and distributed power applications.
