Qorvo introduced a power management integrated circuit (PMIC) that expands the company’s portfolio of products for rapid in-vehicle charging of phones, tablets and laptops. Qorvo’s ACT4751M is the industry’s first AEC-Q100 qualified step-down, voltage-regulator IC dedicated to USB Type-C® Fast Charger applications. The ACT4751M meets all power requirements for USB Fast Charger applications, including the Power Delivery 3.0 Programmable Power Supply (USB PD 3.0 PPS) specification. Unlike competitive converter products, it integrates both the power and analog functions into a single power IC. This approach creates a complete USB Fast Charger solution when combined with a power delivery controller, reducing development time and BOM cost. The self-contained, step-down ACT4751M operates up to 40V and has protection features that withstand up to 48V of load-dump events in demanding automotive environments. A step-down charger provides protection between the power source and the device to mediate differences in the voltage source and the battery being charged. These chargers have become increasingly popular as more applications adopt USB Type-C® ports because they are universal and capable of delivering high power. AEC-Q100 is an industry standard specification established by the Automotive Electronics Council (AEC). In addition to its AEC-Q100 qualification, the ACT4751M meets the automotive EMI standard CISPR 25 Class 3 with patented DC-DC conversion technologies.
