Disassembly report: Anke 140W USB pd3.1 gallium nitride charger

2024-09-15

Anke launched its first USB pd3.1 charger, which is also a gallium nitride charger. This charger supports 140W high power output and is internally equipped with gallium nitride HFB architecture. Built in innovative stacking technology and customized devices, the power density is greatly increased and the volume is significantly reduced.

This 140W charger adopts the same Infineon HFB + IgAN scheme as the previously disassembled full gallium nitride 120W three port gallium nitride charger, which supports wide voltage output without built-in buck conversion circuit and has higher output efficiency. The following charging head network will disassemble the 140W all gallium nitride charger of Anke in detail to see how the internal design is.

Before that, the charging head network has also disassembled products such as Anke full gallium nitride 120W charger, Anke 100W 2c1a gallium nitride super charge, Anke 65W 2c1a gallium nitride super charge, Anke 45W gallium nitride super charge, Anke 30W gallium nitride super charge. Please check them.

Anker's latest all gallium nitride 140W charger has strong output performance and is compatible with QC, PD and PPS mainstream fast charging protocols. It can meet the needs of MacBook Pro 2021 notebook and can obtain the same fast charging experience as the original charger. PFC + HFB circuit architecture is adopted internally, which has the advantages of high performance and small volume.

Among them, the PFC boost controller adopts Anson ncp1623, which is equipped with nano micro gallium nitride power chip nv6136a, and the HFB half bridge is composed of Infineon xdps2201 hybrid flyback controller and igi60f1414a1l half bridge gallium nitride chip, which provides a solution with higher integration, smaller volume and higher energy efficiency for gallium nitride fast charging.

The output protocol chip adopts Weiquan wt6676f, which supports a wide working voltage range of 3.3V ~ 45V, supports USB PD 3.1 SPR and epr36v specifications, has rich interfaces, and supports overheating protection and PFC control. The interior of the charger is welded with multiple PCBs, and the thermal conductive adhesive filling process is adopted to enhance the heat dissipation performance, improve the mechanical strength and weather resistance, make full use of the space and reduce the volume of the charger.
