MaxLinear, announced the introduction of a modular intelligent power management solution for next-generation broadband SoC designs. The platform consists of the MxL7080 power management controller, MxL76500 smart regulating stage (SRS) modules, and the MxL76125 22V / 15A synchronous buck regulator.
The solution targets high-bandwidth, multi-service access platforms including DOCSIS 4.0 cable gateways, fiber (HGU) gateway designs, Ethernet and Wi-Fi home routers, DSL and G.fast CPE, and Fixed Wireless Access (FWA) gateways. It addresses requirements for scalable multi-rail power delivery, higher power density, tighter voltage tolerances, and improved thermal performance in complex SoC designs.
The MxL7080 controller paired with four MxL76500 SRS modules provides a reference-based multi-phase power architecture. Key features include scalable multi-phase power delivery for high-current SoCs, improved thermal distribution to reduce localized hot spots, simplified PCB layout and routing flexibility, and precise multi-rail sequencing with dynamic voltage scaling support.
The MxL76125 is a 22V, 15A synchronous buck regulator in a 4 × 5 mm QFN package. It features a wide 5 to 22 V input voltage range, fast transient response using COT-based control with ceramic output capacitors, efficiency up to 96 percent with light-load PFM mode, and integrated protection including OCP, OVP, OTP, UVLO, and short-circuit protection.
The complete power solution is designed for platforms supporting multi-gigabit services and Wi-Fi 7 adoption. MaxLinear will demonstrate the solution at the Applied Power Electronics Conference (APEC) 2026 in San Antonio from March 22–26, 2026, at booth 941 and within the DigiKey booth 2219. Demonstrations include a transient performance comparison and a system-level SoC power demo showing the MxL7080 and multiple MxL76500 regulators operating together.
Dr. Amit Bavisi, Senior Vice President and General Manager of MaxLinear’s Analog Mixed Signal Business Unit, stated that power delivery requirements for broadband and connectivity platforms continue to evolve, and the addition of the MxL76125 provides a scalable, thermally robust, and flexible power foundation.
Puneet Sethi, Senior Vice President and General Manager of MaxLinear’s Network Infrastructure and Carrier Business Unit, noted that the SRS-based architecture delivers thermal improvements for next-generation gateways, reducing hot spots and enhancing long-term reliability.
Ken Paxton, Director of Advanced Semiconductor for DigiKey, said MaxLinear’s solutions align with technologies sought at APEC.
The MxL7080, MxL76500, and MxL76125 are available now in RoHS-compliant, green/halogen-free packages. Evaluation boards and samples are available. MaxLinear’s broader power management portfolio also includes the MxL76505, MxL76508, MxL76503, and MxL76502 point-of-load regulators.
The global Power Management IC market was valued at approximately $41.8 billion in 2025 and is projected to exceed $72 billion by 2034 at a compound annual growth rate of approximately 7 percent. MaxLinear’s platform addresses a multi-billion-dollar total addressable market in DOCSIS, fiber, Wi-Fi routers, DSL, G.fast, and FWA gateway designs.
