With the increasing number of smart phones that support fast charging, the feeling of "never going back" after you have used the "fast charging" specification should be impressive. At present, many 110V ~ 240V power chargers have been corresponding to QuickCharge 4 (QC 4.0)& QuickCharge 4.0+ (hereinafter referred to as QC 4.0+) & PD quick charging specifications. . The car? This solution provides the Power Delivery (PD3.0) charging mode of USB Type-C fast charging, so that you can also enjoy the convenience brought by fast charging in the car. The following is a brief introduction of this solution for each IC function.

DC-DC 60W PD3.0 PPS Car Charger EV1 Evaluation Board includes two main parts. The NCP81239 component is a synchronous four-switch buck - boost DC/DC controller capable of adjusting the output voltage above, below or below the input voltage.

The NCP81239 has an input voltage range of 4.5V to 28V and can support a variety of applications. AP43771 is the decoder IC, which will cover USB PD3?? .0 PPS(Programmable Power Supply) and Qualcomm QuickCharge®4/4 + standard,

In order to achieve fast charger decoder function.

Based on monitoring D + and D- and CC1 and CC2 signals, the AP43771 interprets the required voltage and current Settings and then feeds the information back to the NCP81239 switcher to provide a well-regulated VBUS voltage and current and the associated power protection L.

When charging, the voltage can be slightly adjusted according to the state of the device/charger/charging line, which has the advantages of large current and large voltage

Qualcomm Quick Charge 4.0+ (QC4+) -- Compliants with previously published QC4.0, QC3.0, QC2.0 fast charging technology, not only mobile phones can be used, including mobile power, car charger can support QC fast charging specifications. Compatible USB - PD

USB Power Delivery 2.0/3.0 -- USB PD (USB Power Delivery). The charging specification of PD must be through the Type-C interface. There is no limitation on devices, including cameras, tablets, laptops, screens, etc., which can be charged by USB PD.

When using the device that supports PD specification, the maximum wattage can reach 100W (20Vx2A). It supports a variety of schemes up to 100W. It is designed for a variety of devices, and can be used for laptop charging.
