0.5W & 1W Precision, Low-Noise DC-DCs with Linear Regulators and 2kV Isolation

RECOM has added two dc-dc converters to its low power dc-dc portfolio; the R0.5ZX and R1ZX series. The R0.5ZX and R1ZX are based on the 2kVdc isolated low-profile R1SX SMD series but include an internal linear regulator to give a precise, load- independent and low-noise output.

Typical applications include isolated 5V supplies for sensors, bus-interface, and precision test and measurement circuits.

The already low output ripple and noise can be reduced to 2mVp-p with a simple external filter circuit. The output is also continuously short-circuit protected. In the event of a continuous overload or over-temperature condition, the output will shut down, thus protecting the converter and the application from over-current damage.

The output will automatically restart once the fault condition has been lifted. These dc-dc converters operate over an extended industrial temperature range from -40°C up to +100°C and are IEC/EN/UL 62368-1 certified with CB report.

The devices are 0.5W or 1W and all variants feature a Vin of 5Vdc. They all have a Vout of 5Vdc. Variants of the converters have an Iout of either 100mA or 200mA depending on the model, and the devices feature isolation of either 1kV or 2kV.

Samples and OEM pricing are available from all authorized distributors or directly from Recom.
