RECOM develops new SMD Switching Regulator Series
TI announcement to discontinue the production of their Power Trends switching regulators (PT78ST100, 78SR100, etc.) at the end of 2013, and while many of RECOM’s switching regulators are drop-in replacements for the through-hole packages, there were no drop-in replacements for the SMD packages. In order to fill this gap, RECOM decided to introduce the R-78T series: a newly developed, 1:1 compatible SMD product line. This can help avoid costly re-designs for customers who are still using Power Trends switching regulators.
The compact, low profile "Open Frame" modules are based on the well-established R-78-family. Due to their high efficiency of up to 95% and wide input voltage range of 7V to 42V they are a space-saving solution for portable or battery operated applications.
The new R-78T series provides optional regulated 3.3V/1A, 5V/1A or 12V/1A in continuous operation, but can also handle peak currents up to 1.5A for 10s. Thanks to their high efficiency, the modules do not require fans or heat sinks. They can be operated reliably at temperatures between -40°C and +85°C without derating.
The small-sized 23 x 27.2 x 10mm or 23 x 29.4 x 8mm modules are pin-compatible with other 78 series SMD switching regulators and SMD TO-220 linear regulators. They are supplied for fully automatic assembly optional in "tape & reel" or "tray" and are designed for the reflow soldering process. The warranty period is 3 years.
