What made you select the Qorvo ACT85411 as a featured product? What value and differentiation does this product offer?
This month, I’m pleased to highlight the Qorvo ACT85411 Power Loss Protection (PLP) Device as our Power Expert Product Pick. Designed to ensure data integrity and enhance device performance, the ACT85411 seamlessly integrates PLP with Power Management IC (PMIC) technology. This combination is particularly crucial in applications like Solid State Drives (SSDs), where maintaining normal operation during power outages is essential. With its advanced features, the ACT85411 helps safeguard critical data and ensures continuous performance, even in the face of unexpected power loss.
The ACT85411 is a highly integrated and configurable power management IC (PMIC) that combines multiple outputs with built-in Power Loss Protection (PLP). It features two high-efficiency buck regulators capable of delivering up to 12A of peak current and 10A of continuous output current. The output voltage of both buck converters is programmable, ranging from 0.6V to 5.26V. Additionally, the device includes a 12V buck-boost converter with a programmable output range between 9.6V and 15.95V, offering further flexibility in power management for a variety of applications.
In addition to these features, the ACT85411 is equipped with a specialized Low Dropout Regulator (LDO), which can be powered by either the 5.0V VCC output or the VAUX input pin. A dedicated mini-buck regulator is used to convert the 12V input supply to generate a 5.0V output on VCC. The key innovation of the ACT85411 is its built-in Power Loss Protection circuitry, which ensures backup storage power during an input power failure. A high-voltage Boost converter within the device enables efficient energy storage, minimizing the need for large storage capacitors and ensuring reliable operation even in the event of power loss.
