On March 15-17, the Munich Shanghai Electronics Show was exhibited at the Shanghai New International Expo Center. As a major event in the industry, many of them joined the international manufacturers. Liyi Technology is a professional analog IC design company dedicated to providing customers with professional power management solutions and product services. Liqi Technology exhibited Type C and USB PD solutions at the show.
Liqi Technology's new USB type-c product series
With the rapid development of USB3.1 technology, Liqi Technology has proposed AC/DC, DC/DC and electronic tag chips certified by USB-IF Association in order to meet the high-power charging/power supply requirements under the high-speed transmission interface. The complete solution meets the variable output voltage requirements of 3.0V-20V, while also meeting the requirements of safety, efficiency and cost control. The solutions for a variety of end applications have been adopted by the world's largest manufacturers.
RT1710 USB type-c cable electronic label
USB-IF-certified (TID) USB type-c cable electronic tag RT1710, with minimal WDFN-8L 2X3 package, integrates all components required for electronic tags, with 8KV/600V (HBM/MM) electrostatic withstand The ability to operate from -40° to 85° ambient temperature allows cable manufacturers to minimize the size of the PADDLE CARD for easy design.

USB PD solution
Highly integrated AV/DC charger and adapter
Liqi Technology introduced the RT7786+RT7207 as a highly integrated PWM+USB-PD CONTROLLER with many features to enhance the performance of low power flyback adapters. It is equipped with a PWM control chip RT7786 on the primary side and a protocol chip RT7207 on the secondary side. It is optimized for automatic adjustment of system parameters for different output voltages, providing a safer and more flexible USB PD adapter. / Charger solution, and has been certified by the USB-PD Association, can be completed in the most simplified circuit design, achieving low cost, small size, light weight and high power density product design.
Highly integrated solution
The RT7207 single chip on the secondary side integrates USB type-c and PD protocol control, synchronous rectification control, and constant voltage constant current feedback control regulator to help customers significantly simplify the circuit design of the system.
High efficiency performance
When the output voltage is 5V~20V, the system efficiency is over 92%.
Low standby power consumption
The proprietary GREEN-MODE design mode, which is linearly down-converted below the LIGHT-LOAD state, allows the design to easily meet efficiency specifications and safety testing.
High security adapter
The design of the withstand voltage of the secondary side CC PIN is 20V, ensuring that the chip can be instantly protected when it is shorted to VBUS to ensure the system is stable and safe.
