Renesas ISL95855AIRTZ: High-Precision Voltage Regulator Solution Designed For IMVP8™ CPUs

 

In the field of high-performance computing and mobile processors, precision and flexibility in power management are crucial ISL95855AIRTZ, an IMVP8™-compliant 3+2+1 multi-phase voltage regulator. ISL95855AIRTZ provides a complete power solution for microprocessors supporting core, graphics and system agent rails. The controller provides control and protection for three Voltage Regulator (VR) outputs. ISL95855AIRTZ has become one of the core components of modern CPU power supply systems due to its excellent performance and configurability. As a well-known supplier of electronic components in the industry, Mingjiada Electronics has been supplying ISL95855AIRTZ steadily for a long time to provide reliable power solutions for servers, notebook PCs and embedded systems.

 

Core Features Of ISL95855AIRTZ

Multi-phase configurable design

The ISL95855AIRTZ supports three independent outputs (VR A, VR B, and VR C), which correspond to the power supply requirements of the CPU core, graphics unit, and system agent rails, respectively. VR A can be configured for 3-phase, 2-phase or 1-phase operation, VR B supports 2-phase or 1-phase, and VR C is a single-phase design. This flexibility enables it to adapt to different load scenarios and optimise the energy efficiency ratio.

 

High Accuracy and Wide Voltage Range

With an output range of 0V to 1.52V and a system accuracy of ±0.5% over the full temperature range, ISL95855AIRTZ regulator ensures a stable voltage input for processors with the IMVP8™ architecture. Its differential remote voltage detection function further enhances the accuracy of voltage regulation.

 

Intelligent Control and Protection Mechanisms

The ISL95855AIRTZ supports Intel Serial Data Bus Interface (SVID), which can be programmed to implement Dynamic Voltage Regulation (DVID) and a variety of protection functions, including over-current, over-voltage and over-temperature protection. In addition, its lossless inductor DCR current detection and adaptive body diode conduction technology significantly reduces power consumption and response time.

 

High-performance power management

In the PS4 low-power state, the ISL95855AIRTZ has an extremely low quiescent current, effectively extending the life of mobile devices. Its switching frequency can be programmed with external resistors to suit the energy efficiency requirements of different application scenarios.
