The flash 20W PD fast charging charger was disassembled, and the built-in protocol chip was certified by qc4 + of Qualcomm

As we all know, the iPhone 12 doesn't deliver chargers, and various brands have begun to seize the 20W fast charging market. Recently, sharp flash also launched a 20W PD fast charging charger. Although this product supports QC, PD, PPS and other fast charging protocols and has comprehensive performance, it does not continue the unique sharp and tough ID style of flash, but changes to the round edge and straight panel design, Break the fan stereotype. So how is the interior design of this charger? The following charging head network will bring you the detailed disassembly of the charger.

1、 Appearance of flash 20W charger

The color of the box is black, and the front of the box is printed with sharge brand, charger appearance and name.

Charger parameters and business information are printed on the back of the box.

Open the packing box and cover the charger with plastic bag to prevent dust.

The charger adopts PC flame retardant material, black shell, body surface matte treatment, both sides of semi-circular arc design, which is a bold attempt for the flash pole.

The front of the fuselage is equipped with the logo of sharge brand.

The input is equipped with fixed GB pin.

The input shell is printed with charger specification information

There is a usb-c interface in the center of the output top surface, the black rubber core does not leak copper, and there are pd3.0 and 20W marks beside the interface.

The measured length of charger body is 45.73mm by vernier caliper.

The width is 45.92mm.

The thickness is 22.77mm.

Compared with the size of Apple's 20W charger, the flash pole charger has a wider body. The intuitive feeling of charger in hand.

The PWM master chip pn8161 is from chipown. A quasi resonant current mode controller and a power MOSFET are integrated in the chip, which is specially used for high performance AC / DC switching power supply with compact peripheral components. The chip provides comprehensive and excellent intelligent protection functions, including output over-voltage protection, cycle by cycle over-current protection, overload protection and soft start function.

Pn8161 achieves ultra-low standby power consumption and optimal efficiency in full voltage range through qr-pwm, qr-pfm and burst mode hybrid modulation technology and special device low power structure technology. Frequency modulation technology and softdriver technology fully ensure good EMI performance.

Summary of dismantling charging head net

Sharp flash 20W PD charger adopts PC flame retardant material shell, adopts round edge straight panel modeling design, both sides are semi-circular arc surface, increases user's feel, and the input end is equipped with fixed pins, which changes the unique edge and strong ID style of flash. The charger supports QC, AFC, FCP, pe2.0, pd3.0, PPS multiple fast charging protocols, and has a wide range of compatibility. In addition to being compatible with apple family products, many Android models can also get a good fast charging experience, and multiple devices can be considered.
