DC/DC converters add digital monitoring and control
XP Power announces a digital version of its HRF15 series of 15-W DC/DC converters with output voltage and current programming through a PMBus via I2C. These new capabilities address the growing need for automation and remote control in high precision equipment, including mass spectrometry, scanning electron microscopy, and transmission electron microscopy for semiconductor inspection and analytical research.
Compared with the company’s precision analog version launched earlier in 2025, the digital interface of the HRF15 DC/DC converters makes integration simpler, reduces setup time through a graphical user interface, and accelerates product development. Reliability also improves with advanced monitoring and programming.
Other key features include power supply status flags that deliver visibility into system health and performance, enhancing uptime and protecting sensitive instruments; and data logging and real-time diagnostics that converts complex internal data into actionable insights, enabling users to make quick, informed decisions that result in lower operating costs and enhanced application safety. In addition, multi-unit synchronization enables scalable power architectures.
Suitable for noise-sensitive applications, the HRF15 series features extremely low ripple down to 0.001% (10 ppm), critical for high performance. The units exhibit high stability over time at 10 ppm/hr, delivering consistency and repeatability in sensitive processes. Load and line regulation, down to 0.001%, delivers high performance even in load-dependent applications or where input voltage fluctuates. They also have a low temperature coefficient of 25 ppm/°C, minimizing environmental performance influences.
Single-output voltages can be specified at 10 kV, 12 kV, and 15 kV and each unit can deliver 15 W of power from a 24-VDC input. The output rail is fully adjustable for constant current and constant voltage from 0 to 100%, which addresses a wide range of loads.
The HRF15 series carries UL6101O and UL62368 safety approvals. Housed in a case measuring 33.0 × 72.4 × 161.0 mm, and weighing approximately 465 g, the compact units ease integration into space-constrained applications. They are currently available from Avnet Abacus or direct from XP Power with a three-year warranty.
