POL convertor is first with digital control
The DPL20C is a 20A output convertor which features an extensive set of digital configuration, monitoring and diagnostic facilities accessible via the PMBus interface.
Companies currently forming POLA include Texas Instruments, Artesyn, Emerson Network Power's Astec Power and Ericsson Power Modules.
The PMbus is a working group consisting of several power and semiconductor companies that aims to release an open protocol supporting communication to power supplies via a digital bus.
During 2005, the members of POLA intend to release digitally controlled products that are completely interoperable.
In doing so, POLA members' products will offer more advanced features and hence provide the possibility for end users to revolutionise their power management.
Point of load regulators allow more design flexibility when there are many voltages present in the same system.
These devices are particularly useful in complex circuits such as those incorporating ASICs and DSPs that demand power sequencing.
Another factor driving the demand for these products is customers' requirements for multiple sources that have led to the formation of alliances and standards.
POLA is the first alliance that offers completely interoperable products.
