INFINEON PMBUS SUPIRBUCK

PMBus SupIRBuck Voltage Regulators by Infineon

Requirements to optimize efficiency and to address the complex power requirements of CPUs, ASICs and other sophisticated ICs are making active power management a critical design requirement in applications such as datacenter servers, embedded telecoms systems and networking equipment. At the same time, engineers tasked with designing power schemes are expected to keep board space to a minimum while reducing the time between initial concept and final product.

To address the challenges of active management, engineers are increasingly considering digital power schemes built around the PMBus specification, which offers a standardized platform for monitoring and controlling power management devices. And to address the real estate issue they are looking to implement these schemes with the lowest possible number of components. Highly integrated digital power converters with built-in PMBus support provide a way for designers to meet both sets of challenges.

Infineon’s NEW PMBus SupIRBuck™ is an easy-to-use, fully integrated and highly efficient DC-DC regulator with I2C/PMBus interface. The on-board PWM controller and MOSFETs make the family a space efficient solution, providing accurate power delivery for low output voltage and high current applications.
