operational downtime. For large power conversion systems,


high level digital control makes it possible to manage power parameters reactively to meet the current demands of the system and the operation as a whole. The ability for reliable remote


management of power supplies improves the scalability of your business as PMBus allows for the power supplies to communicate with other companion chips. Any adjustment or modification needed can be made a simple software routine and transmitted digitally to multiple systems. Other benefits of digital power include:


• Wider stable operating ranges • Tighter unit-to-unit repeatability as


through digital control, designers can eliminate loop inconsistencies caused by analogue components


• Configurations can be downloaded • Reducing system cost as virtual power components can be formed


• Automated adjustments result in better consistency


PRODUCTS One of the ultra-compact DC-DC converters making full use of the PMBus standard is the CHS80 from Cosel. Alongside a built-in remote on and off feature, the use of PMBus allows this converter to be managed, configured and monitored remotely through digital control. As a DIP package, the CHS Series is


available in industry standard brick sizes for easy installation onto a PCB – making it ideal for use in the telecommunication market. This compact power converter also includes built-in overcurrent, overvoltage and thermal protection circuits for added redundancy and safety. Through its PMBus interface, the


CHS80 can communicate with other chips on a board, allowing system designers to create reactive power management schemes through communications from other chips in a system. With efficiency of up to 95%, and a


wide operating temperature range of -40 to 85 degrees Celsius, the CHS80 is perfect for designers looking for an adaptive and versatile power supply delivering up to 80W of power. The Artesyn iHP is where digital


control is taken to the next level. For system designers looking for complete control and sequencing of key parameters in a demanding power level


application, Artesyn’s state of the art precision high power system offers the remote control needed for true central management of a large, sprawling power network.


mentioned earlier in the article. In the name of Precision Digital control is perfect for any


application where rapid, on-the-fly adjustments need to be made to multiple system parameters. Beyond output voltage and monitoring system temperatures, bespoke and open standards like PMBus allow for the flexibility in managing key fault data and creating predictive power sequences. Digital power has its place in high-


power critical applications (like affording the pinpoint power precision needed for medical equipment) as much as it’s useful for low-power applications where the added efficiency and development time and cost savings are more evident. Affordable power modules like the


The PowerPro configurable GUI allows


end users to seamlessly control and monitor all functions, including monitoring fault data, system temperature and set detailed routines. Where Artesyn’s integration of the I2C


standard improved on the precedents set by the use of PMBus is with its GUI, system designers can use a graphical script creation engine allowing for user- friendly control and maintenance. Multiple iHP systems can be controlled


from one central controller through a remote GUI accessed on a local network, furthering the benefit of added scalability


CHS80 show that digital power has its home in low-cost and compact applications demonstrating that digital control supplies have the capable rate of adoption to become the dominant method of power management in the power supply industry. Rapid and flexible configurability makes


our digital control range the perfect place to start to cut the development, deployment and operational costs of your next system.
