IEC 62368-1 introduces a new hazard-based approach to safety engineering that gives designers extra flexibility to demonstrate compliance, and 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.
By also offering 1kVDC or 3kVDC isolation-voltage options, this series presents an ideal solution 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 full -40°C to 100°C temperature range.
Variants are available with 3.3V or 5V inputs, and a single unregulated 3.3V or 5V output. Capable of operating at up to 78% efficiency, they also have quiescent consumption of less than 150mW thereby minimising dissipation and easing system thermal management.
By adopting an industry-standard pinout, R1SX modules provide a drop-in replacement for the R1S series, with 50% lower mounted height.
Class A EMC compliance can be reached without external inductors, and only a simple external filter is needed to achieve Class B compliance.
