Infineon Technologies has announced that its digital PoL DC/DC regulators with full PMBus capabilities are featured in the Kintex UltraScale development board. A key driver for the design flexibility of the board is the superior PMBus connectivity of the company's IR3806x family. Configurations can be stored in internal memory and PMBus commands allow run-time control, fault status and telemetry.

The on-chip programmable SupIRBuck regulator provides tremendous flexibility for FPGA-based design, easily adapting to rapidly changing design requirements. The IR3806x SupIRBuck voltage regulator integrates a PWM controller and MOSFETs in a single package. It delivers 90% more efficiency for all rails including all losses and less than 10mV peak-to-peak ripple from 3 to 35A. The regulator allows system power management on a high level and is extremely robust.

Despite its compact footprint, 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, enabling designers to easily design and verify applications.

The Xilinx BERT demonstrates error losses through rigorous code testing, using 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.

Infineon will show the Xilinx Kintex UltraScale board in booth #1917 at APEC, 20th to 24th March 2016 in California, USA.
