Beilande Launches “One Core and Two Charges” EPP Certification Scheme D9622: Supporting PD Dual 15W Wireless Charging!
Recently, the charging head network learned that Beilande has recently released a “one core and two charges” scheme D9622. This scheme supports PD dual 15W and digital demodulation anti-jamming. The two outputs are compatible with 5W, 7.5W, 10W and 15W, and support the wireless fast charging of apple 7.5W, Samsung 10W and Huawei 10W, which can charge two mobile phones or one mobile phone plus an AirPods headset simultaneously.
First, Beilande released the “one core and two charges” program
With more and more electronic devices at hand, users who charge two or more devices at the same time are increasingly demanding. In addition, the Type-C interface is becoming more and more popular, and the USB PD fast charging protocol is also the general trend and gradually becomes the mainstream. For wireless charging, products that support dual devices for wireless charging at the same time and USB PD fast charging input naturally have no small market demand. In order to meet this market demand, Beilande officially released the “one core and two charges” scheme D9622.
Beilande’s “one core and two charges” scheme adopts a D9622 master control and two D9015 power full bridges, which is highly integrated. Its main features include: supporting PD protocol input, dual 15W output power, and digital demodulation anti-interference. The total output power is up to 30W(15W*2), each channel is compatible with 15W, 10W, 7.5W and 5W protocols, and supports dual 15W wireless fast charging of two mobile phones (Apple 7.5W, Samsung 10W, Huawei 10W, etc.). The transmitter has QC2.0/QC3.0/PD identification function, and the input not only supports the common QC fast charging protocol, but also is compatible with the current USB PD fast charging protocol.
Second, Beilande D9622: fully synchronous digital demodulation wireless TX charging chip
Detailed specifications and parameters of Beilande fully synchronous digital demodulation wireless TX chip D9622 are as follows:
- Integrated PD3.0(PPS)/QC3.0/AFC fast charging protocol, supporting Apple/Samsung full range PD/QC fast charging head
- Adaptive input voltage, no adapter
- Integrated 32-bit ARM processor with 100MHz frequency, PWM frequency up to 200MHz. The industry’s top processor
- rich memory and pin resources, meet various customization requirements
- support USB online update Firmware without special programming device
- multi-channel fully synchronous digital demodulation, unique Wave-Monitor technology, ensure communication reliability
- support WPC standard Type architecture such as MP-A11/MP-A2/A28/A11.

Third, the world’s first one-core dual-charge EPP certification scheme
Beilande’s one-core dual-charge scheme has obtained WPC wireless power consortium EPP certification, which is also the first one-core dual-charge wireless charging scheme obtained EPP certification in the world, and has great advantages in compatibility and stability.
Generally speaking, to realize one-to-many wireless chargers, two MCU chips are needed, while only one Beilande is needed. One main control IC controls two sets of circuits, which is anti-jamming for digital demodulation and supports PD dual 15W wireless charging, with strong performance. The “one core and two charges” scheme has been shipped in batches in many first-line e-commerce brands, and customers in need can contact Beilande.
