MaxLinear Introduces a 15A Step-Down Switching Regulator With 2-Bit VID to Power High-Speed Digital and RF Systems

March 20, 2023
  • MxL76125 designed and qualified to provide power to the digital core of MaxLinear’s single-chip Wi-Fi 7 solution

CARLSBAD, Calif.--(BUSINESS WIRE)-- MaxLinear, Inc. (Nasdaq: MXL) today announced the release of MXL76125, a 15 Amp Step-Down Switching regulator with 2-Bit VID designed and qualified to provide power to the digital core of MaxLinear’s Wi-Fi 7 SoCs. With this release, MaxLinear further leverages its extensive power management expertise to provide solutions that simplify system architecture.

With the integration of a 2-Bit VID into the MXL76125, the Wi-Fi 7 SoC can communicate to the power supply, adjusting its core voltage depending on the power needs of the system. This level of system operability across MaxLinear chipsets allows end users to implement power savings modes and meet stringent market requirements without additional cost or complexity.


Customer Premise Equipment (CPE) and enterprise networking manufacturers face significant challenges during Wi-Fi FCC qualification testing in designing and building Wi-Fi 7-enabled home gateways and wireless networks. One key example is passing Wi-Fi FCC qualification where the quality of power delivery can directly impact the results. The MXL76125 has been designed to meet the needs of MaxLinear Wi-Fi 7 SoCs, the MXL31712 and MXL31708, providing a fast and stable power supply with low noise. By offering a complete and proven solution, customers can be assured that the power delivery is optimized for their system needs.

“With the release of the MXL76125, we’re able to offer CPE developers a reliable and complete Wi-Fi 7 networking and power solution,” said James Lougheed, Vice President & General Manager, High Performance Analog & Accelerators. “MaxLinear is able to leverage expertise across numerous technology groups to produce highly integrated solutions that can give our customers a clear advantage in the marketplace.”
