he TSR1SM series models of step-down switching regulators (non isolating β POL) have a high efficiency up to 96 % which allows full load operation up to +65Β°C ambient temperature without the need of any heat transmission layer.
Excellent output voltage accuracy (Β±2%) and low standby current (~1 ΞΌA) 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 245Β°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 β free registration required) with max. peak body temperature 245Β°C. Also low MSL level 1 allows PCB washing after soldering with baking at 100Β°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 donΒ΄t hesitate to contact us at [email protected].
