Wired switching regulator

8 October 2014 Power Electronics / Power Management

The latest product from Recom supplements the R-78 switching regulator family. The R-78W – a wired version of the R-78 – is mainly intended for use in applications which utilise few or no printed circuit boards.

For instance, in LED lighting solutions, a constant voltage for a fan can be generated by connecting the switching regulator in parallel with the LED driver. Additionally, in prototyping and in many areas of electrical engineering, wired regulators are extremely advantageous.

Standard output voltages of 5 V, 9 V or 12 V with an output current of up to 500 mA are available. This module offers not only a wide input voltage range of 6,5 V to 32 V but is also short circuit protected via shutdown with auto-matic restart. It is safe to use in industry standard operating temperatures with an operating temperature range of -40°C to +85°C.

To further protect this regulator, a protection diode is integrated into the module in order to prevent damage from reverse currents when switching off. Due to its compact design (17,5 x 11,5 x 8,5 mm) the R-78W is also suitable for use in portable and battery-operated devices. Due to its high efficiency of up to 96%, no heatsink is required, saving valuable board space and lowering mounting costs.
