SupIRBuck's PMBus connectivity allows for design flexibility

Infineon Technologies AG has released Digital Point-of-Load (PoL) DC-DC regulators that have full PMBus connectivity, allowing for flexibility in FPGA-based design. The IR3806x family of regulators are used in the Kintex UltraScale development board. They enable configurations to be stored in be stored in internal memory, as well as run-time control, fault status and telemetry.

The on-chip programmable SupIRBuck regulator easily adapts to rapidly changing design requirements. It features integrated PWM controller and MOSFETs in a single package. It delivers 90% more efficiency for all rails, including all losses and 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.
