Maxim Integrated Products has launched the MAX6948B white LED driver IC with switching frequency up to 2MHz. It can drive string lights with up to 6 LEDs in series. The maximum current that can be supplied is 30mA. Mainly used for driving backlights for LCD panels and LEDs for mobile phones.
The main wiring material in the network integrated wiring system is the Network Cable, including twisted-pair cable, optical fiber, optical fiber and so on.In order to protect the wiring line, ensure the neat and beautiful wiring place, but also to facilitate the later operation and maintenance, the integrated wiring system will also use some accessories, such as distribution frame, information socket, jumper, cabinet and frame, wire slot, pipe and bridge frame, finishing tools, etc.

This product is a driver IC using a step-up DC-DC converter circuit. Integrated n-channel power MOSFETs eliminate the need for external products. Due to the high switching frequency, small parts can be used for external components. Therefore, the mounting area on the printed substrate can be reduced.
Dimming is also available. After setting via the I2C interface, the brightness of the LED can be adjusted using a 10-bit PWM signal. The brightness can be adjusted to 1024 levels. In addition, there are five GPIO (General Purpose Input/Output) terminals with low output current. Can drive 1 LED. The output current of the two GPIO terminals is 30mA, and the output current of the other three terminals is 20mA. The GPIO terminal is also equipped with an 8-bit dimming function.
White LED driver IC with switching frequency up to 2MHz
In human discharge mode (HBM), electrostatic discharge (ESD) withstand voltage ensures ±8kV. The power supply voltage is +2.7 to 5.5V. The operating temperature range is -40 to +105 °C. The package uses a 25-terminal WLP (wafer levEL package) with a mounting area of ​​2.31 mm × 2.31 mm. When the 1000 batches are purchased, the unit price in the US starts at $1.70. 
patch pannel is used for end-user line or trunk line. Its function is to provide interface for the connection of optical cable, cable and other equipment. It is the most important component in the management subsystem, and also the hub to realize the cross connection of vertical and horizontal trunk subsystems.
Depending on the location, the distribution frame is divided into main distribution frame and intermediate distribution frame, in which the main distribution frame is used for the distribution of buildings or buildings, and the middle distribution frame is used for the distribution of floors.According to the different transmission medium, distribution frame is divided into twisted-pair distribution frame and optical fiber terminal box.
