Product Description

16V 4.5A Notebook Power Supply For Lenovo

For the replacement adapter choise, we need check the PCB carefully, followed are some components information:

1. Varistor, its function is when the external voltage is too high, the varistor resistance quickly become very small, and varistors in series with the fuse is blown to protect other circuits are not burned.
2. Fuse, specifications 2.5A / 250V, when the circuit current is too large, the fuse will fuse to protect other components.
3. Inductance coil (also known as choke), the main function is to reduce the electromagnetic interference.
4. Rectifier bridge, specifications for the D3SB, the role is to 220V AC into DC.
5. Filter capacitor, specifications for the 180μF / 400V, the role is to filter out the DC in the AC ripple, the circuit work more reliable.
6. Operational amplifier IC (integrated circuit), protection circuit, an important part of voltage regulation.
7. Temperature probe, used to detect the internal temperature of the power adapter, when the temperature is higher than a certain value (different brands of power adapter, the set temperature threshold is slightly different), the protection circuit will cut off the adapter voltage Output, thus protecting the adapter from damage.
8. High-power switch, Switching Power Supply is one of the core components, switching Power Supply can "open one" to work, switch tube contributed.
9. Switch transformers, switching power supply in one of the core components.
10. Secondary rectifier, the function is to low-voltage alternating current into low-voltage direct current. In IBM's power adapter, the rectifier is often operated by two high-power shunts in order to obtain a larger current output.
11. Secondary filter capacitor, specifications for the 820μF / 25V, a total of two, from the filter in addition to the role of low-voltage direct current ripple.
In addition to the above components, the circuit board also has adjustable potentiometer and other resistance element.
