New dc/dc converters in a SOIC-16 package feature 5-V (4.5-5.5 V) inputs and a semi-regulated 5-V output are rated at either 0.5 W (R05C05TE05S) or 1 W (R05CTE05S). Line and load regulation figures are specified across the full temperature range, and there is no minimum load requirement, making the parts ideal for applications that have light-load operation modes.
Both parts have a 3 kVdc/1 min (basic) insulation rating with greater than 8-mm input/output creepage and clearance, and operate from -40 to 125°C with derating. Isolation capacitance is just 7 pF. Protection features include short-circuit, over-current, over-temperature, and input undervoltage, making the parts highly suitable for applications that demand a high level of reliability and robustness. EMI levels are also particularly low compared with more expensive competing products.
The SOIC-16 package fits in a 10.35×7.5-mm footprint and 2.5-mm profile, perfect for space-constrained designs. The two parts are pin-compatible, allowing future upgrades from 0.5 to 1 W if necessary. The dc/dc converters are also partially pin-compatible with the higher specification RECOM R05CT05S, which includes 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/dc converters 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”.
