1, Zhilong 25W superThe scheme is based on the design and development of Smarong's latest super fast charge mobile power chip SW6208 and wireless charging chip SW5100. The mobile power part continues the excellent performance of SW6208. One chip solves a variety of complex functions such as lifting voltage control, protocol recognition, 5 charging interface control, LED power display, etc. Its biggest feature is to support 25W super fast charge.

Super I/O chip is also called I/O chip. There are I/O control circuits on the motherboards above 486 grades. Because there must be resource mismatch between high-speed devices such as South Bridge and a large number of low-speed devices such as serial, parallel interfaces, floppy disk drives and keyboards and mice, they need to be converted and managed. The Super I/O chip completes this function.
cannot be replaced directly. Its role is to connect a resistor or capacitor to set the operating frequency. Instead, it has six legsIC pins are the same function, check whether there is a circuit connected to the 3 pin when replacing, if not, connect a 100K resistor to the ground in the 3 pin, replace with OB2263, the circuit can work. If there is no peripheral circuit in the case of 3 pin with OB2263 replacement will cause explosion.
is a six-pin patch chip that is very common. 6-pin switching power oscillator chip, also known as power management chip. It is widely used in LED color TV power board, various chargers, DVD players, set-top boxes and electric car chargers.
The main role of AC-DC power module is to convert alternating current (AC) to direct current (DC), usually this process includes rectification, filtering and voltage regulation several key steps. The functions and roles of this module include: voltage conversion: Alternating current of different voltage levels, such as common household electricity 220V or 110V AC, can be converted into one or more low-voltage direct current required by electronic equipment, such as 5V, 12V, 24V DC, etc.
AC/DC/The power flow can be bidirectional, the power flow from the power supply to the load is called "rectification", and the power flow from the load back to the power supply is called "active inverter". DC/DC/DC: The use of microelectronics technology, the small surface mount integrated circuit and miniature electronic components assembled into one.
Once the chip is started, the output voltage of the winding provides continuous power to the chip. Once the chip starts working, the GATE foot drives the switch tube to open or close, and each output winding has voltage output. The switch tube source is connected with a current sampling resistor, and the sampling voltage is sent to the chip CS pin when the current reachesWhen the design maximum value is reached, the CS pin voltage is greater than the reference voltage set inside the chip, the GATE pin voltage becomes low, and the switch tube is turned off.
The role of the switching power supply is to convert a level voltage into the current or voltage required by the client through different forms of architecture. The switching transistor used by the switching power supply switches between the fully open mode (saturation region) and the fully closed mode (cut-off region), both modes have the characteristics of low dissipation, and the conversion between the switching will have a higher dissipation, but the time is very short, so it is more energy saving and produces less waste heat.
