MXL7080-AQB-R

Overview

The MXL7080-AQB-R is a specialized power management controller designed for MaxLinear AnyWAN SoC URX800/600 and Puma 8 DOCSIS 4.0 systems. It controls four MxL76500 synchronous buck regulator rails via an I2C interface. The device features dynamic voltage scaling (DVS) using DAC outputs ranging from 0.6V to 1V and 3V to 3.6V. It manages start-up sequences, power sequencing, and fault monitoring. The component is housed in a QFN-32 4x4 package.

Feature Summary

• Controls four MxL76500 synchronous buck regulator rails
• Provides dynamic voltage scaling via dedicated DAC outputs
• Manages system start-up, power sequencing, and fault monitoring
• Interfaces with MaxLinear AnyWAN and Puma 8 SoCs

Applications

• Power management for MaxLinear AnyWAN SoC URX800/600 series
• Power management for MaxLinear Puma 8 DOCSIS 4.0 SoC systems
• Multi-rail power sequencing for high-performance communication processors

Procurement Notes

Verify the specific suffix 'AQB' matches the required package and tape-and-reel configuration. Confirm compatibility with the target SoC generation, as this controller is optimized for URX800/600 and Puma 8 platforms. Ensure the design supports the required I2C interface and DAC output ranges for proper DVS operation.

Selection Notes

Select this component when managing power for MaxLinear's AnyWAN or Puma 8 SoCs requiring coordinated multi-rail control. It is suitable for designs needing integrated sequencing and dynamic voltage scaling without external sequencers. Verify that the application requires the specific voltage ranges supported by its DAC outputs.
