Why to pay for the current, which you won´t use?

Switch-mode regulator Traco TSR 0.5 will give you as much as you need. If you have an application, where 0.5A is sufficient, then the new series of DC/DC modules is ideal for you.
This is an archive article published 01/02/2015. Some information may no longer be up to date and in line with the current state. Please contact us in case of interest.

Maybe, it´s worth to ask a question, whether it makes sense to use a switch-mode regulator for such a low current? For sure yes, at least because of two reasons. If we need to create 3.3V from for example 12V, then at a current of 0.5A a power loss of 4.35W appears at a classic linear regulator. That´s already a quite considerable power, able to heat up a device - especially at smaller enclosures and a dense population on a PCB.

Another reason is energy saving - especially at battery powered devices. Switch mode power supplies (SMPS) have a “genial” feature, that thanks to their high efficiency we use practically whole power drawn from a source, i.e. if we need say 5V/0.5A from a 15V source - we won´t take from it 0.5A but only approx. 0,17-0,18A.

Novelty of company Traco Electronic - series TSR 0.5 is by its function very similar to well known, proven DC/DC regulators TSR1 or TSRN1. The main difference is in a smaller allowed current and a feelingly lower price . That ´s why this series is very suitable for any application, where a current of 0.5A will be sufficient. A big advantage can be a wide operating temperatures range from -40 to +90°C (power derating 5%/K at temperature above 80°C). Maximum input voltage of 32V enables a usage even at power supplying from various alternative energy sources with a big input voltage fluctuations.

This novelty is so far available in a version with 5V output voltage (TSR 0.5-2450) and soon there will be another.

In case of interest even in non-stock types, please contact us at info@soselectronic.com.
