The front of the PCBA module is at a glance, and two hollow slots are inserted into the isolation plate for insulation.
At the back of the PCBA module, the left side of the isolation slot is the primary master chip, switch tube and optocoupler, and the right side is the synchronous rectification chip, protocol chip and VBUS switch tube.
It is observed that the charger adopts the QR switching power supply scheme, and the protocol chip adjusts the output voltage through optocoupler feedback. Let's start from the input to understand the information of each device.
The specification of input delay fuse is 2.5A 250V, and it is protected by heat shrink tube.
After passing through the fuse, the AC input is sent to the vertically welded small board for rectification and filtering. The small board is welded with common mode inductance, rectifier bridge, filter capacitor and differential mode inductance.
Common mode inductance is wound with insulated wire and enameled wire, with insulated support welded at the bottom and insulated with heat shrink tube.
The back of the small plate is welded with a rectifier bridge and coated with gray thermal conductive adhesive for heat dissipation.
