Artesyn Unveils DPL20C Digital POL DC-DC Converter
Artesyn Technologies Inc. (Boca Raton, FL), a manufacturer of power conversion and embedded board solutions for infrastructure applications in telecommunications systems, unveiled its first digital point-of-load (POL) converter, the DPL20C, which is a non-isolated POL converter in the new family of PMBus-compliant dc-dc converters. The DPL20C is intended for computing, storage, and networking applications.
The DPL20C is a 20 A output converter that features an extensive set of digital configuration, monitoring, and diagnostic facilities accessible via the PMBus interface. The converter stores all configuration and set-up data in non-volatile memory, and powers-up with these pre-programmed default settings, thus eliminating the need for external power controllers. The DPL20C is rated for forced-air environments with ambient operating temperatures of 0 °C to +70 °C, seen in the latest 1U-high rack-mounting equipment.
Functionality includes a wide input range from 4.5 V to 13.8 V; a programmable output voltage from 0.6 V to 5.5 V; programmable sequencing, tracking, and margining; real-time monitoring of voltage, current, and temperature, with automatic warning of fault conditions; ability to source/sink 20 A of load current, along with differential remote sensing; a library of 45 executable PMBus commands; and a Windows-based GUI supporting a variety of personal computer interfaces.
The DPL20C is the first of many PMBus-compliant power conversion products that Artesyn will be introducing. Future products will encompass different current ratings and mechanical form factors, as well as feature increasingly higher levels of digital control and integration. Sampling of the product along with evaluation boards to the first Beta customers has now begun; general availability and production will commence upon completion of Beta trials, expected within the next 45 days. The general market release of the new DPL20C converters will be in October.
