Wide-input isolated converters deliver flexibility with space savings

08-07-2019 | Dengrove | Power

For cost-sensitive applications where board space is at a premium, Dengrove Electronic Components offers the new RECOM REC15E-Z isolated DC-DC converters featuring a 4:1 input-voltage range and compact 1”x1” footprint with built-in protection.


The choice of 9V-36V or 18V-75V input range enables the converters to work with all standard industrial bus voltages from 12V to 48V, as well as popular battery types such as lead-acid or lithium. Inputs are protected against transients up to 100V to ensure robust performance in electrically noisy conditions, and UVLO averts over-discharging of batteries.


Capable of operating at up to 90% efficiency, these 15W converters provide full power from -40C to 75C with no derating. There is also no minimum load demand. Single- or dual-output configurations are available, covering popular 3.3V, 5V, 12V, 24V, ±12V, or ±15V voltages to address a wide range of applications. The outputs can run high-capacitive loads and feature built-in continuous protection against short-circuit and overload conditions.


Customers are able to select the converters with a 3.3V, 5V, 12V, or 24V single-ended output or ±12V or ±15V dual outputs. Further options incorporate an external on/off control pin and a trimming pin to adjust the output voltage up or down with an external resistor. The outputs feature built-in continuous protection against short circuit and overload conditions and can drive highly capacitive loads.


With 1.6kV isolation the converters ensure safety in demanding applications. They are certified to the latest IEC/EN/UL 62368-1 safety standard and come with a three-year manufacturer’s warranty.
