65W PD adapter with cable complete solution

This HP1510+HP3501+HUSB381A 65W PD adapter with cable combo solution, AC-DC controller and fast charging protocol chip are both from Hynetek's latest R&D products.

The reference design solution supports Type-C port with cable and 65W PD adapter output, which can charge IoT devices, mainstream cell phones, tablets and computers in the market.AC-DC adopts Hynetek's HP1510+HP3501 power solution, which supports multiple operating modes of DCM, QR and CCM, making the design more flexible. With secondary Schottky short circuit protection, transformer saturation protection, output over-voltage, input over-voltage, over-temperature and other comprehensive protection makes the application more secure. The fast charging protocol part is paired with Wisers' HUSB381A, which is specially designed for wireline PD adapter applications. The peripheral is simple, and the built-in switching MOSFETs make the PCB layout simpler and more efficient. The reference design solution adopts single-sided PCB design and supports wave soldering and red glue process, so the processing cost can be maximized.
