PDC004 12V PD Decoy Module - USB-C to 12V DC Fixed Voltage Trigger Board (IP2721)

Product Description

The PDC004 12V PD Decoy Trigger Module is a specialized hardware component designed to "trick" a USB-C Power Delivery (PD) charger into outputting a fixed 12V DC signal. Unlike standard USB-C cables that default to 5V, this module uses an onboard IP2721 identification chip to perform the digital handshake required to unlock higher voltage rails. It is an essential tool for repurposing modern USB-C power banks and adapters to power non-USB devices such as routers, LCD monitors, and soldering irons. The module is strictly a "sink" device, meaning it requests power but does not regulate it; therefore, the output voltage is entirely dependent on the capabilities of the connected PD power source.

Key Features

• Hardware-Level Negotiation: Uses a dedicated 2721 chip to ensure a stable, hardware-defined 12V trigger without needing a microcontroller or software.

• High Power Throughput: Supports up to 5A of current, enabling it to deliver up to 60W or 100W depending on the charger's rating.

• Compact Integration: One of the smallest decoy modules available, making it easy to embed directly into device housings or custom cable assemblies.

• Onboard Status LED: Features a success indicator light that illuminates only when the PD handshake is completed and the 12V rail is active.

• Safety First Design: Includes VBUS short-circuit protection to prevent CC pin burn-in during testing and deployment.

Technical Details

• Protocol Compatibility: Fully compliant with USB Power Delivery 2.0 and 3.0 specifications for universal charger support.

• Fixed Voltage Logic: This 12V model is hardwired to request only 12V; it will not support PPS (Programmable Power Supply) or variable voltage selection.

• Auto-Fallback Feature: If the connected charger does not support 12V, the chip will intelligently request the next lowest available voltage (typically 9V) to maintain safety.

• Solder Pad Layout: Large, pre-tinned solder pads for V+ and V- allow for heavy-gauge wire attachment for high-current applications.

• Input Connector: High-quality Type-C female socket designed for thousands of insertion cycles.

• Current Loss Minimization: Optimized PCB traces reduce resistance, ensuring maximum power transfer from the charger to the load.

• No Heat Generation: The 8-bit hardware processor consumes negligible power, ensuring the module stays cool even under heavy loads.

• Universal Application: Ideal for converting laptops, networking gear, and small household appliances to USB-C power.

• Reserved Positioning Slot: Includes a physical notch in the PCB for secure mounting inside DIY project boxes.

• Data Line Isolation: Data pins are isolated to prevent any interference with the host charger’s internal communication.

• Non-Upgradable Firmware: The hardware-based logic is permanently etched, providing a "set and forget" solution for 12V power needs.

• Voltage Verification: Always use a multimeter to verify the output before connecting sensitive equipment.

• High-Quality PCB: Built on a durable FR-4 substrate with a solder mask to prevent accidental shorts.

• Low Profile: The ultra-thin design (5mm height) allows for low-clearance installations.

• Reliable Connection: Supports both forward and reverse USB-C plug insertion with automatic signal detection.
