This demonstration shows 2 examples of AC/DC solutions for efficient fast battery charging.

Firstly a slim 25W USB PD + QC adapter built with NXP latest chipset solution. The adapter will demonstrate a fully USB PD (Power Delivery) and QC (Quick Charge) compliant solution charging a true PD device (Apple macbook air / Google Pixel notebook or Google SP) or a QC smartphone (e.g. Samsung S6 edge).

Secondly a compact 33W Direct Charging adapter built with NXP latest chipset solution. The adapter will demonstrate a fully compliant direct charging solution charging a true HiSilicon FSP device, supporting the FSP charging protocol like a Huawei smartphone

Furthermore will be demonstrated the system configuration and debug features of the secondary controller by using NXP Graphical User Interface (GUI) and control board.

 

 

Features:

  • Best-in-Class overall efficiency – meets all DOE & EU-CoC regulations
  • Smallest form factor / highest power density due to high efficiency
  • High integration level & very low BOM cost - minimum number of external components
  • Very flexible system due to on-chip DSP and memory – Fully meets USB-PD, QC, FSP/SCP protocols
  • Main functionality (V & I & protections) configurable by programmability of key system parameters
  • All protections integrated in hardware – OVP, OCP, OPP, OTP, various short circuit conditions
  • Low cost and suitable packages for both reflow and wave soldering
  • Optional tamper resistant authentication chip allowing own eco-system specific accessories
