20 A digital POL converters

19 August 2009 Power Electronics / Power Management

Power-One has announced two new high-efficiency digital point-of-load (POL) converters, the ZY2120 and ZY8120, in its ZY2000 ‘no-bus’ and ZY8000 'bus-programmable' series, respectively. These Z-One digital POL converters with latest-generation topologies provide 20 A and up to 93% efficiency for server and communications applications.

The converters have an input range from 8 to 14 V with user-defined outputs between 0,5 and 5,5 V over the 0°C to 70°C operating range. The scalable architecture manages up to 32 components, including up to four analog devices. The ZY2120 is hardware configured via pin strapping and trim components. The ZY8120 can be programmed via an industry-standard I2C bus or a wizard-driven graphics user interface (GUI). When used with ZM7300 series digital power managers, it facilitates the complete elimination of external components for sequencing, tracking, protection, monitoring and reporting.
