SY8823QUC Description

Short technical summary and product information.

The Silergy SY8823QUC is a synchronous step-down DC-DC regulator designed for high efficiency and ultra-low quiescent current. It can deliver a maximum output current of 3.5A and operates over a wide input voltage range of 2.5V to 5.5V. The device features a switching frequency of 2.0MHz, which helps in achieving fast transient response and allows for the use of smaller external components.

Key electrical characteristics include a typical quiescent current of 18uA and low on-resistance for internal switches (55mΩ for PFET and 35mΩ for NFET), minimizing conduction losses. It also includes hic-cup mode protection for hard short conditions and a 100% dropout function.

The SY8823QUC is housed in a compact QFN2x1.5-8 package, suitable for space-constrained applications. Its design makes it suitable for applications such as Set Top Boxes, Net PCs, Mini-Notebook PCs, and Access Point Routers.

This regulator is RoHS compliant and Halogen Free, aligning with environmental standards. The package thermal resistance is 100°C/W for junction-to-ambient and 15°C/W for junction-to-case.
