YINGHUA USB5434JZX4 VQFN64 semiconductor

USB5434JZX4 VQFN64 semiconductor component

The YINGHUA USB5434JZX4 is a semiconductor integrated circuit supplied in a VQFN64 package. It serves engineers and procurement specialists sourcing ICs for USB-related circuit designs. The part is stocked as new inventory and first appeared on the manufacturer listing on 21 February 2025.

Thermal, noise and power characteristics

As a bare integrated circuit, the device generates heat proportional to its switching activity and load conditions. It operates silently because it contains no moving parts or cooling hardware. Power draw depends entirely on the surrounding circuit implementation and the USB traffic pattern it handles.

Integration requirements and board-level benefits

The VQFN64 footprint requires a compatible PCB land pattern and reflow soldering process. Designers must provide appropriate decoupling, signal routing and thermal vias as dictated by the datasheet. Using this IC consolidates USB functionality into a single package, freeing board space that discrete solutions would otherwise occupy.
