Campbell Collins Uniquely Positioned to Demonstrate 3E Digital Converters & Regulators to UK Customers
Campbell Collins Ltd, a specialist supplier of power supplies, capacitors and power semiconductors, announces today that it is in the unique position of being able to fully demonstrate Ericsson Power Modules’ range of Digitally Controlled DC/DC Converters and Point of Load Voltage Regulators using the latest version of the 3E Evaluation Kit and software.
EricAll four of these product families utilise Digital Power Management techniques, enabling full communication and control between individual devices and the customer’s on board host controller. These functions are implemented using the industry standard two wire PMBus interface, which is compatible with I2C. A further benefit of using Digital Power Management is the increase in Power Density and Efficiency over their Analogue counterparts. The BMR450 20A regulator for example has a footprint of just 1” x 0.5” and delivers efficiency levels of up to 96.8%.
Using the FAP 901 0755/2 Digital Evaluation Board and associated Silver Edition GUI interface, Campbell Collins can demonstrate to its customers the complete functionality of the Digital Management techniques. From a monitoring/reporting standpoint, this includes, but is not limited to, reporting of the input voltage level; output voltage; output current and internal junction temperatures. From a digital control standpoint, the converters and regulators can be programmed via the PMBus interface to modify certain parameters such as the output voltage; soft start/stop levels; delay and ramp-up times and voltage/current/temperature warning and fault levels, including modifying whether the unit should have latching or auto-restart protection. Additionally, the software can be used to pre-program voltage margining levels for production and qualification testing purposes.
