Cost-efficient SOIC-16 range added to family of DC-DC converters

RECOM has extended its range of DC-DC converters in a SOIC-16 package with new versions, which provide even better value. The parts feature 5V (4.5-5.5V) inputs and a semi-regulated 5V output rated at 0.5W (R05C05TE05S) or 1W (R05CTE05S). Line and load regulation figures are specified over the full temperature range, and there is no minimum load demand, making the parts excellent for applications having light-load operation modes.

Both parts have a 3kVDC/1 min (basic) insulation rating with higher than 8mm input/output creepage and clearance and operate from -40C to 125C with derating. Isolation capacitance is only 7pF. Protection features comprise short-circuit, over-current, over-temperature, and input undervoltage, making the parts extremely suitable for applications that require a high level of reliability and robustness. EMI levels are also especially low compared with more expensive competing products.

The SOIC-16 package is only 10.35mm x 7.5mm footprint and 2.5mm profile, ideal for space-constrained designs. The two parts are pin-compatible, allowing future upgrades from 0.5W to 1W if necessary. The DC/DCs are also partially pin-compatible with the higher specification R05CT05S, which incorporates features such as remote on/off and reinforced isolation.

Applications for the two ranges include isolated COM port power supplies, gate drive power, current sensing/smart metering, medical devices, industrial PLC (I/O), and sensors for IoT/IIoT.

“These new DC/DCs are a low-cost alternative when all the features of our higher spec SOIC-16 parts are not needed,” commented Matthew Dauterive, DC-DC product manager of RECOM. “Even so, they still are manufactured with the same automated process with advanced transformer fabrication technology for the highest reliability in critical applications.”
