ACT88911 Multi-Rail Power Management IC

 The Qorvo ACT88911 is a compact, highly integrated power management IC designed for systems requiring multiple precision power rails and efficient sequencing. It combines five buck regulators, two buck-boost regulators, two boost regulators optimized for LED drive, and ten LDOs/load switches in a 3.76 mm × 4.16 mm WLCSP package.

Supporting an input voltage range of 2.7 V to 5.5 V, the ACT88911 offers dynamic voltage scaling, configurable startup sequencing, and multiple low-power modes to optimize system efficiency. Its I²C interface enables full programmability for voltage, timing, and operating modes without hardware changes, making it ideal for space-constrained designs.

With advanced fault protection, GPIO-based system control, and autonomous LED modes, this PMIC simplifies power architecture for high-performance platforms such as AI processors, FPGA-based systems, and computer vision applications.
