Qorvo Provides USB Fast Charger PMIC for In-Vehicle Mobile Devices [Copy link]

A power management integrated circuit (PMIC) that expands the company’s product portfolio for fast in-vehicle charging of phones, tablets and laptops. The Qorvo ACT4751M is the industry’s first qualified USB-C step-down regulator IC for fast charger applications.

“The proliferation of connected car devices with advanced in-cabin infotainment systems requires more power ports at higher power levels,” said David Briggs, senior director of Qorvo’s Programmable Power Management business. “Qorvo’s AEC-Q 100 qualified power IC, the ACT4751M, is a unique and easy-to-use step-down product that features the smallest size and highest efficiency on the market.”

The ACT4751M meets all power requirements for USB fast charger applications, including the Power Delivery 3.0 Programmable Power Supply (USB PD3.0 PPS) specification. Unlike competing converter products, it integrates power and analog functions into a single power IC. This approach creates a complete USB fast charger solution when paired with a power delivery controller, reducing development time and BOM cost.

The self-supplied, step-down ACT4751M operates up to 40V and features protection to withstand load dump events up to 48V in demanding automotive environments. Step-down chargers provide protection between the power source and the device to mediate the difference between the voltage source and the battery being charged. These chargers are becoming more popular as more applications adopt USB-C Type-C ports because they are universal and capable of delivering high power.

AEC-Q 100 is an industry standard specification established by the Automotive Electronics Council (AEC). In addition to its AEC-Q 100 certification, the ACT4751M meets automotive EMI standards CISPR 25 Level 3 with patented DC-DC conversion technology.

Qorvo's automotive power management portfolio supports faster design certification and reduces time to market by offering multiple reference designs for USB fast chargers and Qualcomm Quick Charge 3.0, Quick Charge 4 and Quick Charge 4+. These designs are fully optimized to minimize size while providing maximum power conversion efficiency.

The ACT4751M is available for sampling now; specifications are below.
