RFMW Expert Product Pick: Qorvo ACT88911 Multi-Rail PMIC

What made you select the Qorvo ACT88911 Power Management IC as a featured product?

I selected the Qorvo ACT88911 highly integrated power management IC because it delivers the kind of dense, flexible, and efficient power architecture that is essential for today’s AV and AI processing systems. Whether you are designing for computer vision, AR or VR headsets, or FPGA-based platforms, your power architecture needs to be compact, highly efficient, and dynamically configurable. These systems often demand multiple precision power rails, fast transient response, and low power operation, all within limited board space and strict thermal budgets.

The ACT88911 addresses these challenges with a feature-rich design that includes five buck regulators, two buck-boost regulators, two boost regulators optimized for LED drive, and ten LDOs or load switches. Two of the buck regulators can be configured for dual-phase operation to deliver up to 10 amps. Offered in a compact 3.76 x 4.16 mm package, it reduces external component count and simplifies power system design. Its I²C interface enables full programmability and real-time monitoring, while configurable GPIOs support system-level control, LED drive, and custom interrupt schemes. With support for dynamic voltage scaling, flexible startup sequencing, and multiple fault protections, the ACT88911 stands out as a robust and space-saving solution for advanced SoC-based applications.
