Units of the RLS line inductor series have been pre-tested to meet both conducted and radiated interference limits. It is often necessary to add additional filter components to a dc/dc converter module to meet Class A or Class B EMC limits. To build such an EMC filter, inductors from a range of different manufacturers can […]

Low power dc/dc converters boast precise outputs
RECOM has extended its low power DC/DC portfolio with 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. The already low output ripple and noise can be reduced to […]
DC/DC converters feature 4:1 input, compact 1×1-in. footprint
The recently released REC15E-Z series of 15-W isolated dc/dc converters features wide input ranges at low cost in the widely used 1×1-in. case size. This saves a significant amount of PCB space, while the wide input ranges increase flexibility by accepting several standard bus voltages. The REC15E-Z dc/dc converters are fully-specified devices with 15-W, no […]
12:1-input quarter-brick dc/dc converters key on railway apps
Two 40-W and 60-W dc/dc converter series come in quarter-brick packages with an ultra-wide input voltage range of 14 to 160 Vdc making them a good candidate for railway rolling stock applications and high voltage battery systems. The 12:1 input voltage range of RECOM’s RP40Q-RUW and RP60Q-RUW series covers all input voltages from nominal 24 […]
Reference design for galvanically-isolated CAN transceiver
The R-REF03-CAN1 Reference Board demonstrates the ISO1042 isolated CAN transceiver supplied by the R1SX-3.305/H isolated dc/dc converter. To supply the reference board only one 3.3-V external supply is required. The green LED indicates the presence of the VCC2 supply on the secondary (CAN bus) side. The reference board allows designers to quickly develop and analyze […]
Eval boards check power modules for trimming, sequencing, soft starts and sensing functions
RECOM’s eval boards for the RPM‐1.0, RPM‐2.0, RPM‐3.0, and RPM‐6.0 buck regulator series generate a constant output voltage with an output current up to 6A from an external DC source. The multitude of functions offered by the RPM power modules such as trimming, sequencing, soft‐start, enable, and sensing can be evaluated. More importantly, the behavior […]
Modular dc supplies target smart home and IoT apps
The RAC15-K and RAC20-K series are designed for low-power IoT and household applications. These ac/dc modules have ultra-low energy losses especially in light load conditions and minimal standby power consumption. Based on the footprint of the compact RAC10-K modules, these new modules feature high-efficiency over a wide load range. This makes them candidates for the […]
Low-profile DOSA converters hit 99% efficiency
New power modules offer one of the highest power densities in a DOSA footprint on the market with a profile of only 3.75 mm. They provide either 1, 2, 3, or even 6 A in the same-sized package for scalability. The 6-A module has at least 50% higher power density than its peers on the […]
AC/DC modules provide 5 W for Industry 4.0, IoT and smart home apps
The RAC05-K/277 series includes 5 W ac/dc converters that support peak power needs and are specially designed for extended input lines and reliable operation at extreme temperatures from -40°C up to an impressive +90°C. The RAC05-K/277 series are built to operate from extended input lines with mains voltages from 85 Vac up to 305 Vac, […]
Low-cost 2-W dc/dc converters offer high isolation
The RKZE series is a cost-effective 2-W dc/dc converter in an industry standard SIP7 case. The extended operating temperature range runs from -40° to +95°C, making these converters suitable for demanding environments in industrial, test and measurement applications as well as high-volume manufacturing. They are pin-compatible with the RK and RH converter series, offering a […]
