Unregulated DC/DC converter is 20% slimmer
The surface mount, isolated converter is 20% slimmer than alternative converters, claims the company, and the open frame modules measure 12.75 x 10.8mm. With an industry-standard pinout, R1SX modules provide a drop-in replacement for the R1S series, with 50% lower mounted height.


They satisfy EN 55022/024 and IEC/UL/EN 60950-1 and are certified to the upcoming IEC/UL/EN 62368-1 safety specification. IEC 62368-1 introduces a new hazard-based approach to safety engineering that gives designers extra flexibility to demonstrate compliance. It is expected to replace the established IEC 60950-1 rules.


R1SX converters can drive capacitive loads of up to 2200µF, which is 40 times higher than comparable alternatives, according to the company. By also offering one or 3kV DC isolation-voltage options, the series can be used for isolating CAN-bus connections to ensure equipment safety and preserve signal integrity. They can also be used to power loads in equipment such as industrial automation controllers, without derating, over the -40 to 100°C temperature range.


Variants are available with 3.3 or 5.0V inputs, and a single unregulated 3.3 or 5.0V output. Capable of operating at up to 78% efficiency, they also have quiescent consumption of less than 150mW, minimising dissipation and easing system thermal management.


Class A EMC compliance can be reached without external inductors, and only a simple external filter is needed to achieve Class B compliance.
