V SCP fast chargeIt also supports 66W (11V/6A) and is compatible with multiple gears. FCP and PD Fixed also remained at 18W (9V/2A).
The fast charging protocols of the charging treasure include Huawei's SCP fast charging protocol and Qualcomm QC protocol. Huawei SCP Fast Charge Protocol The full name of Huawei SCP Fast Charge Protocol is Super Charge Protocol, and the full name of FCP Fast charge protocol is Fast Charge protocol.
SW is short for switch, which refers to the switch pin of the power chip. The power chip is the core of the power management of electronic devices, where the switch pin controls the high and low levels, thus switching the operating state of the device. The state of the SW pin directly affects the voltage output of the device, so the stability and efficiency of the power chip are related to the design of the SW pin.
SW is the Switch pin. FB is the FeedBack pin. COMP is the Compensation pin. OSC is a crystal oscillator, an oscillator(Oscillator) pin.
SW Pin is the switch output pin pin, also called the pipe pin, English called PIN. That is, from the internal circuit of the integrated circuit (chip) to the wiring of the peripheral circuit, all the pins constitute the interface of the chip. A section at the end of a lead that is soft brazed to form a solder joint with a pad on a printed board.
CS is Current sense (current detection, current sampling, current feedback); COMP is the Compensation pin; FB is Voltage fVoltage feedback (eedback); GND indicates ground; SW is the Switch pin; FB is the FeedBack pin; OSC is the Oscillator pin.
EN Enable pin, generally high level to make the chip work. VIN power input BS self-boosting pin, SW switch control pin FB output voltage feedback pin COMP comparator input N/C chip is not connected to the N SS power supply.
SW pin is generally the output foot of the power switch, and is often connectedTo the Drain terminal of the MOS inside the IC.
1. The firmware is faulty. Bluetooth, wireless network WiFi, flight mode and other modules appear aging or welding. Collision or fall caused damage to some modules of the motherboard.
2, most mobile phone users will be equipped with a case for their iPhone, but some third-party casesIn particular, the metal protective shell or metal frame shell will affect the signal of Wifi. If the mobile phone Wifi signal is not good, may wish to take off the protective case to try to see if it is better.
3, the analysis is because of the design problem of the WiFi chip itself, the power it can withstand is limited, and after the release of IOS0, the working parameters of the WiFi chip are improved, resulting in the increase of the power of the WiFI chip during work, resulting in the high temperature of the WiFi chip after long-term use, resulting in the performance attenuation of the WiFi chip.
4, Apple wifi signal weak reason: mobile phoneThe case affects the Wifi signal. Many users give their apple a protective shell, but some third-party protective shells will affect the signal of Wifi. If you have a bad signal, you may want to take off the case and try. Restore network Settings.
1, the exquisite design of the main circuit: limiting, filtering, rectification, inverter and output rectification, each link is indispensable, they work together, like a dancer on the stage, precisely regulate the rhythm of the voltage.
2, but also consider electrical design, electromagnetic compatibility design, thermal design, safety design, three defense design and other aspects. Because even the smallest negligence in any aspect can lead to the collapse of the entire power supply, we should fully realize the importance of reliability design of power products.
3, transistor current control, MOS tube belongs to voltage control, BJT amplifies the current, FET converts the gate voltage to drain current.
4, in the design of high-power switching power supply, in order to prevent the impact of high inrush current at startup, soft start circuit is often usedDo not focus on the introduction. The rectifier and filter circuit adopts the full-bridge rectifier circuit, as shown in Figure 6 below.
5, in the design of switching circuits, the main concern is switching frequency, switching efficiency and transient response performance. In the design of filter circuit, the main concern is the filter effect and cost. In the design of the output circuit, the main concern is the output accuracy and ripple.
The Chinese character printed input and output logo on the side reflects the intimate details, indicating that it only supports the characteristics of fast charging, and the unilateral display lamp is simple and easy to understand. Flip to the back, Sule quality to create a unique painting decoration, giving the charging treasure unique "face" design.
The front design of the power bank is unique, with a fast charge coil, optimized for iPhone 12, even with the shell can be firmly adsorbed. It supports powerful fast charging features, including 25W wired and 15W wireless fastCharging, compatible with a variety of wireless charging standards, to meet the needs of multiple devices.
