(often branded as Product Schematic ) is a high-speed 6-port USB charging station popular among electronics repair professionals for its real-time digital display. While "exclusive" schematics are rarely released by the manufacturer, technical breakdowns reveal it is built on a standard Switch Mode Power Supply (SMPS) topology optimized for multi-channel output. Core Circuitry and Features

The device functions as a centralized power hub with several protective layers: Input Stage

: Features standard EMI filtering and line rectification. It typically includes a fuse (F1) and a thermistor (R12) to protect against inrush current and surges. Power Conversion

: Uses a transformer and bridge rectifier (often 1N4007 diodes) to convert AC mains (100-240V) to stable DC. Intelligent Identification

: Each port is equipped with an IC that automatically identifies connected devices (mobile phones, GPS, tablets) to deliver the correct amperage, supporting Quick Charge (QC) 3.0 Digital Monitoring

: A dedicated controller drives the LCD, which displays the voltage and current for each active port, serving as a diagnostic tool during device repair. Common Repair & Troubleshooting

Because these units are often left on 24/7 in repair shops, they encounter specific failure points: Dead Unit (No Power)

: Often caused by a blown primary fuse or a failure in the bridge rectifier diodes. Inaccurate LCD Readings wlx896b schematic exclusive

: Usually linked to the voltage feedback loop, which commonly employs a precision shunt regulator and an optocoupler for isolation. Faulty USB Ports

: Physical wear or shorted protection diodes on individual channels can cause specific ports to fail while others remain functional.

Current Sensing Resistors: Each output typically has a 0.1-ohm current sense resistor in the 0V line to facilitate the digital readout. Protection Circuits:

Integrated protection against over-voltage, over-current, and short circuits. Parallel Output Design:

Most standard ports are wired in parallel, while the fast-charging ports (QC/PD) have dedicated controller ICs to negotiate higher voltages (5V/9V/12V). LS Electric WLX-896B Schematic Overview | PDF - Scribd

The WLX-896B (often associated with the Product Schematic brand or the SS-304D model) is a multi-port USB desktop charging station. It typically features 6 USB ports with a total output of 40W. Core Circuitry and Components

Based on technical teardowns of similar WLX units, the internal architecture generally consists of two primary circuit boards: a power supply board and a front panel display/output board. Primary Side (Mains):

Protection & Filtering: Features a fuse, a common mode coil, and a bridge rectifier to convert AC to high-voltage DC.

Switching: Utilizes a mains switcher transistor (often mounted on a small heatsink) and a flyback transformer.

Control: Regulated by a switching controller IC with optocoupler feedback for voltage stability. Secondary Side (Output):

Rectification: High-speed rectifier diodes (on a large heatsink) convert transformer output to 5V DC.

Filtering: A bank of roughly five output capacitors and an inductor smooth the power before it reaches the ports. Related search suggestions: I will now provide some

Current Sensing: Uses low-ohm resistors to measure current for the real-time LED display. Technical Specifications Input AC 100-240V, 50-60Hz (Universal) Total Power Output (Standard) DC 5V / 8A shared QC 3.0 Port Supports 5V/3.4A, 9V/2A, and 12V/1.5A Display

The WLX896B is a mixed-signal wireless transceiver SOC (assumed) targeting low-power IoT nodes. The schematic reveals a compact, modular architecture optimized for range, power efficiency, and integration with host MCUs. Key functional blocks: RF front-end, PLL/VCO, low-noise amplifier (LNA), TX PA, RX mixer, IF filtering, ADC/DAC, baseband DSP, power management, and GPIO/peripheral interfaces.

If the WLX896B is a protection IC (similar to DW01 or 8205A combo), a basic schematic would include:

The board uses a tiny 26MHz crystal (X1) and a 32.768kHz RTC crystal (X2). The exclusive note from the schematics: The WLX896B will not start if the 32.768kHz crystal is missing even if the main 26MHz is present. This is because the PMIC uses the low-speed clock for its power sequencing FSM.

Fix: Scavenge a 32.768kHz cylinder crystal (Citizen CFS-206) and solder it to pads X2. Your "dead" board may spring to life.
