DC/DC converters in SOIC-16 package feature medical-grade isolation

RECOM announces the launch of its R05CT05S low-cost 0.5W DC/DC converter in a tiny SOIC-16 package

RECOM, industry leader in power conversion, has set a new price-point standard for a high-isolation, high power density, 0.5W DC/DC converter in a true SMT IC package that can be handled and placed like other surface-mount devices. The R05CT05S has a nominal 5V input (4.5 – 5.5V) and provides a fully regulated, low-noise output, settable by resistor to 3.3 or 5VDC for direct connection to the load or alternatively 3.7 or 5.4VDC to power a downstream LDO for ultra-low noise applications.

Operating with just convection cooling, full output power is available from -40°C to +55°C with only 20% derating at 110°C. Maximum ambient temperature is 140°C.

Market-leading isolation of the R05CT05S is 5kVAC/1min, achieving reinforced/800VAC rating to IEC 62368-1 and 2MOPP/250VAC rating to IEC-60601-1 for medical applications up to 5000m altitude. Isolation capacitance is particularly low at 3.5pF typical, making the part very suitable for applications with high common-mode, switched voltages such as high-side gate driver power supplies.

Along with a 2.5M hours/55°C MTBF rating, comprehensive protection and control features are provided, including short-circuit immunity, over temperature shutdown, and under-voltage lockout, while the part can be synchronized to an external clock and disabled with low standby current by using an ON/OFF control.

The SOIC-16 package of the R05CT05S is in a compact 10.3mm x 7.5mm footprint with a low profile of 2.6mm, leveraging an internal 3D power packaging construction with advanced planar transformer technology and fully automated manufacturing.

“The R05CT05S is a breakthrough product for us”, commented Matthew Dauterive DC/DC Product Manager of RECOM. “The part is offered at a price-point where it can be considered for general use such as in COM port or industrial PLC I/O power isolation, IoT/IIoT sensors and smart metering as well as in more critical application areas such as gate drives, medical and industrial, where the high shock, vibration, temperature and isolation ratings are a real benefit”.
