Highly efficient POL converters

20 February 2008 Power Electronics / Power Management

Power-One has added six new high-efficiency digital POL converters to its ZY2000 No-Bus and ZY8000 bus-programmable series.

These Z-One POLs provide from 5 to 40 A for server and communications applications, augmenting the high-current-density 60 A models that are also available.

Like all Z-One POLs, these new products integrate power management and conversion to significantly reduced board-level parts count, improve power-system performance, and enable advanced power-management functionalities.

The devices employ latest-generation topologies to provide up to 94% efficiency, and the wide input range of 8 to 14 V, combined with user-defined outputs of 0,5 to 5,5 V, reduces the number of different model numbers in the series. The scalable architecture manages up to 32 components, including up to four analog devices.

ZY2000 No-Bus POLs are hardware configured via pin strapping and trim components. These products support power management without the cost and complexity of third-party controllers and communications-bus interfaces, enabling power management with no additional cost or space requirements when compared to analog 'conversion only' solutions.

ZY8000 POLs can be programmed via an industry-standard I²C bus, or a wizard-driven GUI. When used with ZM7300 Series Digital Power Managers, these POLs are said to facilitate the complete elimination of external components for sequencing, tracking, protection, monitoring and reporting.
