Power loss in enterprise systems can result in the destruction or corruption of critical data, often leading to staggering financial and productivity impacts, and permanent damage to a company’s reputation.
Industry leaders are turning to Qorvo’s ActiveCips™ family of advanced PLP products.
Qorvo’s ActiveCips™ family of advanced PLP products
PLP ICs are designed for use in solid-state drives (SSDs) and other applications where detecting
imminent power loss and supplying back-up power quickly is critical to uninterrupted operation of the system.
Qorvo’s PLP products ensure that there is enough time following a power loss for the storage or computing system to back up mission-critical data. Qorvo’s industry-leading integration and its ability to customize circuits, make it easy for designers to solve challenges unique to enterprise storage and computing applications including:
With a wide range of input voltages, Qorvo’s ACT family of PLP ICs offers highly integrated power loss protection solutions by incorporating high-voltage capacitors to store energy and generate a readily available back-up power source. These PLP solutions include a hot-swap compatible e-Fuse that limits inrush current during hot-swap and supports a smooth and reliable power-up sequence.
When the host power supply or main input power supply is lost, the back-up energy stored on high-voltage capacitors is tapped to provide uninterrupted power to the system.
CiPS solutions from Qorvo® offer:
• A high degree of configurability in setting power loss detection thresholds
• Health monitoring that ensures adequate backup power is available
• Storage capacitor health check and aging checks
• Current and voltage measurements for telemetry
This flexibility aids system designers in optimizing size, cost and performance metrics, and allows customizable solutions for a multitude of applications and need-based optimization.
A built-in boost converter provides high-voltage energy storage to minimize storage capacitor size requirements. The same power stage is operated in boost mode to boost the input voltage to a higher voltage and the energy is stored to output storage capacitors. Upon loss of input power, the same power stage and regulator is operated in “buck”, or step-down, mode to draw power from the storage capacitors
and discharge them to provide power to the system. The built-in buck converter regulates the storage voltage to a fixed output voltage that can be used by the system to continue operating even after the input power is lost. The boost/buck regulator contains internal, back-to-back FETs to provide bi-directional input to output isolation. The IC also provides hot-swap and inrush current control.
