Dongguan, Guangdong, China, 21st Jul 2025 – CE-LINK, a global leader in consumer electronics manufacturing, has unveiled its next-generation power solution: the PD3.1 GaN Zero Standby Power (ZSP) Charger, available in 45W and 67W models. Featuring an advanced circuit design, the charger achieves standby power consumption of less than 5mW—fully compliant with the latest DoE Level VII (U.S. Department of Energy) and IEC energy efficiency standards.

Triple Intelligent Power Management

The ZSP solution features a multi-mode dynamic power management architecture that intelligently divides system operation into three distinct phases, optimizing energy efficiency across varying load conditions:

1. Active Mode

When a device is connected and charging, the system enters full power output. It employs high-efficiency synchronous rectification (SR) technology, combined with GaN (Gallium Nitride) and advanced silicon-based MOSFETs, achieving a conversion efficiency of over 90%. This significantly reduces conduction losses while supporting the PD3.1 fast charging protocol, making it compatible with smartphones, tablets, laptops, and other devices.

2. Standby Mode

When a device is fully charged but remains connected, the system automatically shifts to a low-power standby state. Using Dynamic Load Detection (DLD) technology, the system continuously monitors output current. If the current falls below a defined threshold (e.g., 5mA), the main power circuit shuts down, leaving only essential monitoring circuitry active. In this mode, standby power consumption is reduced to under 30 mW—over 50% more efficient than conventional designs.

3. Deep Sleep Mode

When no device is connected for 20 minutes, the charger enters an ultra-low power deep sleep mode. All non-essential ICs (such as PWM controllers and protocol chips) are entered into sleep mode, retaining only a microamp-level wake-up circuit.

In this mode, standby power consumption is reduced to below 5mW—approaching the theoretical minimum and cutting energy use by over 90% compared to traditional chargers (typically 10–50mW).

Intelligent Wake-Up: A dedicated sleep pin detects device insertion signals and reactivates the AC-DC main circuit in less than 100ms, ensuring a seamless, delay-free user experience.

Green Engineering for a Low-Carbon Future

The ZSP architecture is more than just a technical milestone—it embodies a forward-thinking approach to sustainable product design. By reducing standby power consumption to near-zero levels, the ZSP charger effectively lowers grid load, cuts carbon emissions, and minimizes environmental impact. As global energy regulations evolve, the ZSP GaN charger meets and exceeds the latest standards, offering a future-ready solution that actively addresses the problem of passive energy waste.

Versatile Application Scenarios

• Consumer Electronics: Ideal for smartphone chargers, laptop adapters, and smart home power supplies where energy efficiency matters.
• Industrial: Suited for IoT devices, security systems, and sensors that remain idle for extended periods.
• Public Infrastructure: Perfect for hotels, airports, and public charging stations where devices are frequently left unplugged, ensuring minimal energy loss during idle periods.
