Design win; Infineon’s PMBus power chips, on Avnet/Xilinx development platform

March 21, 2016 // By Graham Prophet
Infineon Technologies’ digital point-of-load (PoL) DC-DC regulators with full PMBus capabilities are featured in the Avnet Xilinx Kintex UltraScale development board; the board uses the PMBus connectivity of the IR3806x family. Configurations can be stored in internal memory; PMBus commands allow run-time control, fault status and telemetry.

The on-chip programmable SupIRBuck regulator provides flexibility for FPGA-based design, adapting to rapidly changing design requirements. The IR3806x SupIRBuck voltage regulator has integrated PWM controller and MOSFETs in a single package. It delivers increased efficiency for all rails with less than sub 10 mV peak-to-peak ripple from 3 to 35A, in a tiny footprint. The regulator allows system power management on a high level and is extremely robust.

 

Despite being compact, the IR3806x family delivers a fully integrated PoL regulator with advanced power management programmability, margining, sequencing, and telemetry across multiple rails via full PMBus 1.2 compatibility. The board includes all functions for an embedded processing system. This enables designers to easily design and verify applications.

 

The Xilinx Bit Error Test (BERT) demonstrates error losses through rigorous code testing. It uses worst case bit patterns across serial transceiver/receivers. The IR38060 delivers precise power performance: zero bit error test results show no contribution to jitter noise across the pattern.

 

The Xilinx Kintex UltraScale Development Kit provides a complete development platform for designing and verifying applications based on the Xilinx Kintex UltraScale All Programmable FPGA devices. The Xilinx Kintex UltraScale development board packages all the necessary functions needed for an embedded processing system.

 

Available with the Kintex UltraScale XCKU040-1FBVA676 device, the Kintex UltraScale kit enables designers to prototype high-performance designs, while providing expandability and customisation through the FMC HPC expansion slot and PMOD headers. In addition to the Xilinx Kintex UltraScale XCKU040 device, the Kintex UltraScale development board features 1GB DDR4 SDRAM, two SFP+ interfaces, dual QSPI Flash memories, HDMI interface, LVDS touch panel interface, two 10/100/1000 Ethernet PHYs, and a USB-UART port.
