UPD300 program notebook conversion line highlights:

唯一 The only single chip in the industry to implement E-Mark & ​​PD SNK two-in-one functional solution

⦁ E-Mark 5A current, maximum 100W power carrying capacity

⦁ Ultra low power consumption, high current charging is not hot, safe and reliable

⦁ Software configurable, power strategy, output voltage can be manually configured to generate firmware for easy production

⦁ Support a variety of traditional laptop charging interface, voltage can be matched, strong compatibility

⦁ Support online upgrade of chip firmware in cable head

⦁ Chip supports low power sleep mode

⦁ The chip is certified by USB-IF, TID No. 1000123

USB-IF authentication chip

It can be seen from the POWER-Z test that the UMD UPD300 internally writes multiple sets of PDO report files to meet the needs of different decoy line voltage customization requirements. In addition, according to U-Tech engineers, it is also possible to customize special voltages such as 19.5V to meet the charging needs of different notebook devices.

Support true high power charging

MeasuredThinkPadCharging, up to 73W high power, it can be seen that the E-Mark chip has identified more than 60W of power. The ordinary conversion line can only work at less than 60W, which can not provide the best charging speed for the notebook.

Laptop conversion line advantage

The picture on the left is the most common application scenario at present. Users need to carry multiple chargers on business trips, which adds extra burden to the journey. Now, using Weiwei Technology to release the PD&E-Mark 2-in-1 traditional notebook PD charging line mass production solution, Simply carry a USB PD charger to solve the charging needs, convenient and simple.

Compatible with 12 major interfaces

Taking into account the many forms and voltage platforms of the notebook interface, the USB-C to laptop charging conversion line developed based on UPD300 can be flexibly handled. It is worth mentioning that the mass production of such notebook charging conversion lines allows the latest USB PD chargers and old notebook computers to blend together, and continue to use the value of the old products, which is conducive to reducing electronic waste pollution.
