The existing features of the standard Recom R-78 series of switching regulators (high efficiency, small case size and pin compatibility with 78-series linear regulators) have been improved by adding a higher input voltage range of up to 42 DC and double the output power in the same size case. The R-78C series offers 15 W/cm³ of power.
Although the device has an efficiency of 96% when the input/output voltage variance is only a few volts, it still reaches 90% with an input voltage that is 30 higher than the output voltage.
The regulator has low output ripple (20-40 mVp-p) and can meet Class B EMC with a simple low pass filter. The standard output voltage options are 1.8, 3.3, 5, 9, 12 C and 15 V all with 1 A continuous output and 3A peak current. The output is overload and short-circuit protected.
The ambient operating temperature covers the full industrial range of -40 to +85°C and the high conversion efficiency makes heat sinking unnecessary. The converter is EN60950 certified. The MTBF is specified by MIL-HDBK 217F at +25°C with 8.6 million hours.
