SY8089A1AAC Description

Short technical summary and product information.

The Silergy SY8089A1AAC is a synchronous step-down DC/DC regulator designed for high efficiency and compact applications. It can deliver up to 2A of output current and operates over a wide input voltage range of 2.5V to 5.5V.

 

Key features include a high switching frequency of 1.5MHz, which minimizes the size of external components like inductors and capacitors. It also boasts a low quiescent current of 50μA and integrates internal switches with low RDS(ON) (130mΩ top, 85mΩ bottom) to reduce conduction losses. The device includes internal soft-start to limit inrush current and hic-cup protection for short-circuit events.

 

Packaged in a compact SOT23-5 surface-mount package, the SY8089A1AAC is suitable for space-constrained designs. Its applications include set-top boxes, USB dongles, media players, and smartphones.

 

The regulator supports 100% dropout operation and features an output auto-discharge function. It is RoHS compliant and Halogen free.
