Power conversion without the bus

The ZY1015 from Power-One is a programmable step down point of load (pol) dc/dc module, integrating digital power conversion and power management.

The device eliminates the need for external components for sequencing, tracking, protection, monitoring, and reporting, and can be changed by the user at any time during product development and service without the need for a communication bus. Instead, it can be configured using pin strapping, an external trim resistor, and a capacitor.

The horizontally mounted 15A pol converter has a 16 x 32mm SMT footprint and is 8mm high. Capable of working with inputs ranging from 3 to 14V, the device suits low voltage, high density applications with intermediate bus architectures, point of load regulators for high performance dsp, fpga, asic or microprocessor applications, and active memory bus terminators, among others.

The ZY1015 provides a 0.5 to 5.5V user configurable output that can start up into pre biased loads.
Features include sequenced and cascaded modes of operation, programmable feedback-loop compensation, over voltage, under voltage, over current, and over temperature protection.
