Schematic Upd - Wlx-896b

Up to 2.4A or 3.5A per port (subject to aggregate load constraints)

The (often referred to alongside models like the SS-304D) is a popular, high-efficiency 40W 6-port USB smart charger. It is widely used for simultaneously charging multiple devices, offering digital display monitoring for voltage and current.

The primary stage feeds roughly 310V–340V DC (depending on local AC input mains) into the primary winding of the high-frequency flyback transformer.

This stage is responsible for receiving unsafe AC power from a standard wall outlet and smoothing it out before conversion. Wlx-896b Schematic

Remember: every component on that board has a purpose, and the schematic tells its story. Happy repairing.

) of the standard USB ports. These chips emulate native hardware profiles, convincing devices from various brands to pull their maximum supported charging speed instead of falling back to safety defaults. Common Hardware Faults and Troubleshooting

: High-voltage electrolytic capacitors (typically rated at 400V, 47µF to 68µF) smooth out the rectified waveform into a stable ~310V DC bus (assuming a 220V AC input). 2. Flyback Switch-Mode Power Supply (SMPS) Stage This stage handles voltage step-down and safety isolation. Up to 2

Blown primary-side protection circuit components caused by mains power spikes.

The naming convention suggests it is part of a generic OEM family. Multiple brands sell the same internal board under different names, meaning the schematic for a Wlx-896b can often be used to repair similar models like the Wlx-898 or Wlx-902.

This chip regulates the switching of the power MOSFET to maintain a steady output. 2. The Transformer and Rectification Stage This stage is responsible for receiving unsafe AC

Rather than using traditional Schottky diodes which waste significant energy as heat, modern variations of the WLX-896B use an active synchronous rectifier circuit. This features a dedicated controller chip coupled with low-resistance MOSFETs to maximize efficiency and minimize heat generation.

: A combination of multiple low-ESR electrolytic capacitors (typically 10V or 16V, 1000µF) and a small toroidal filtering inductor smooths high-frequency ripple down to clean DC. 4. USB Matrix, Logic, and Display Board

The (often part of the "Product Schematic" brand line) is a multi-port USB smart charging station widely used by electronics repair technicians. While a full, high-resolution internal schematic is proprietary to the manufacturer, the device follows a standard Switching Mode Power Supply (SMPS) architecture designed for high-current 5V output and Quick Charge (QC) protocols.
