Provide a 35W PD dual C-port voltage reduction protocol chip CX2935, and a dual C-port PD power reduction protocol chip solution.

CX2935, 35W dual C port dedicated PD buck protocol chip, this is a built-in protocol function buck converter. 

CX2935 has high integration, small size, stable and reliable performance, and 35W-36W dual C port charging scheme is standard adaptation, free CX2935 samples, CX2935 scheme development and technical support!

CX2935 is an integrated synchronous switch buck converter that supports multiple output fast charging protocols, USB Type-C and PD protocols, Qualcomm QC2.0/3.0/3.0+, Huawei FCP/SCP/HVSCP, VOOC 2.0/4.0 protocol, MediaTek PE, Samsung AFC, USB BC1.2 DCP, and Apple 2.4A charging specifications. It is designed for car chargers, various fast charging adapters Provide a complete solution for power supply equipment such as intelligent row and plug.

CX2935 has the function of automatically identifying the VIN input voltage and adjusting the output voltage based on the input voltage. The CX2935 has a built-in power MOS, with an input working voltage of up to 31V and an output voltage range of 3.3V to 21V. It can provide an output power of up to 65W and can automatically adjust the output voltage and current according to the identified fast charging protocol.

The output of CX2935 has CV/CC characteristics. When the output current is less than the set value, it outputs in CV mode and the output voltage is constant; When the output current is greater than the set value, output CC mode and output voltage decrease.

The output voltage of CX2935 has a wired compensation function, and as the output current increases, it will correspondingly increase the output voltage to compensate for the voltage drop caused by the impedance of the connecting line.

CX2935 specifically integrates LINK ™ Patented technology for internet communication, via LINK ™ The interconnection function can be easily and flexibly applied to multiple Type-C port charging schemes.

CX2935 supports secondary burning and can be upgraded online.

CX2935 has multiple protection functions, including input overvoltage and undervoltage protection, output short-circuit and overcurrent protection, and over temperature protection.

The CX2935 is packaged in QFN4x4-16L.
