Switching regulators have extended input and temperature ranges

Now, the range has been extended with the cost-effective R-78CK-0.5 series, operating to 40V input and over a wider ambient temperature range to +100°C. Output current rating is 0.5A and fixed output voltages available are 3.3V, 5V, 12V, and 15V.

The efficiency of the R-78CK-0.5 series peaks at 96%, allowing an operation to +100°C ambient with no or minimal derating at the minimum input voltage, depending on variant. At higher input voltages, the full 0.5A output can be drawn up to a minimum of +65°C ambient, depending on variant.

Full input under-voltage, short-circuit, and thermal protection is provided, and the parts are certified to IEC/EN 62368-1 3rd edition.
Other enhancements compared with the R-78E series include lower quiescent current, a lower allowable input-output differential voltage for the 3.3V and 5V output parts, and a smaller package size in each dimension while still maintaining the standard pinout.

Matthew Dauterive, DC/DC product manager of RECOM comments: "The R-78CK-0.5 series now addresses wider applications with its higher input voltage rating and wider operating temperature range".
Parts include a three-year warranty, and samples and OEM pricing are available from all authorised distributors, or directly from RECOM.
