Title: CE-LINK Releases Breakthrough Zero Standby Power Charger to Redefine Energy Efficient Charging

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 ManagementThe 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 ModeWhen 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 ModeWhen 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 ModeWhen 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...
