Power-One Introduces 5 – 40A Digital POLs For Server & Communications Applications

Power-One, Inc. introduced six new digital POL converters in its ZY2000 "no-bus" and ZY8000 bus-programmable series. These Z-One® Digital POLs provide from 5 to 40A for server and communications applications, augmenting the high-current-density 60A models that were introduced earlier this year.

These new products are said to seamlessly integrate power management and conversion to significantly reduced board-level parts count, improve power-system performance, and enable industry-leading power-management functionalities.

Additional features include: latest-generation topologies provide up to 94% efficiency; wide input ranges (8 – 14V) combined with user-defined outputs (0.5 – 5.5V) reduce the number of model numbers in inventory; 0 to 70°C operating range with what is described as best-in-class elevated-temperature performance; extremely-scalable architecture manages up to 32 components, including up to 4 analog devices; and high-power-density, low-profile form factors designed for space-critical blade server and communications applications.

ZY2000 No-Bus™ POLs are hardware configured via pin strapping and trim components. According to the company, 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, protections, monitoring, and reporting.

ZY2000 and ZY8000 POLs are priced with 5A models starting at $7.00, and 40A models $16.00, for 1000 pieces. Evaluation models are usually available from stock.
