Power-One, Inc. introduces six high-efficiency 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. They integrate power management and conversion to reduce board-level parts count, improve power-system performance and enable power-management functionalities. ZY2000 No-Bus POLs are hardware configured via pin strapping and trim components. They support power management without the complexity of third-party controllers and communications-bus interfaces. ZY8000 POLs can be programmed via an industry-standard I2C bus or a wizard-driven GUI. When used with ZM7300 series digital power managers, they facilitate the complete elimination of external components for sequencing, tracking, protections, monitoring and reporting.
