Digital SupIRBuck Reduces Time-to-Market

Infineon Technologies AG introduced the PMBus SupIRBuck voltage regulator family. The devices are easy-to-use, fully integrated and highly efficient DC-DC regulators with I²C/PMBus interface. The integrated PWM controller, MOSFETs and Bootstrap diode make them space-efficient solutions, providing accurate power delivery for low output voltage and high current applications. Due to the programmable digital interface with remote testing using telemetry, customers will benefit on up to 90 percent reduced design and test times – allowing significantly shorter time-to-market. Additionally, the highly integrated devices further reduce the board space in the range of 50 percent compared to conventional 2-chip solutions.

The new SupIRBuck voltage regulators are ideal for applications in data centers, network storage, wireless infrastructure, mass computing or industrial automation. The devices can be comprehensively configured via PMBus and the configuration stored in internal memory. In addition, 75 PMBus commands allow precise run-time control, fault status monitoring and telemetry of parameters like V_in, V_out, I_out, T or P_out. The new synchronous buck regulators can also operate as a standard analog regulator without any programming and can provide current and temperature telemetry in analog format.
