1A from the sugar cube sized module

With continuous improvement TRACO unveils the SMD version of enormously successful 1A DC/DC converter, the TSR1SM.

This is an archive article published 03.09.2015. Some information may no longer be up to date and in line with the current state. Please contact us in case of interest.

The TSR1SM series models of step-down switching regulators (non isolating – POL) have a high efficiency up to 96 % which allows full load operation up to +65°C ambient temperature without the need of any heat transmission layer. Excellent output voltage accuracy (±2%) and low standby current (~1 μA) are features that distinguish these switching regulators from linear regulators.

To make a SMD version of such a DC/DC converter is not a simple task, the package should withstand temperatures up to 245°C, used in a lead free soldering ovens. TRACO solved successfully this problem and the TSR1SM is qualified for lead free soldering processes as per J-STD-020D.01 (to find at: www.jedec.org - free registration required) with max. peak body temperature 245°C. Also low MSL level 1 allows PCB washing after soldering with baking at 100°C for 30min.

For applications which require lower supply currents up to 0,5Amps, there is a TSR0,5(SM)series of DC/DC converters with better price level available. If you need our help at selection of a suitable type, please don´t hesitate to contact us at sales@soselectronic.com.
