TL2843DR-8 Overview
The switching controller fits in the 8-SOIC (0.154, 3.90mm Width) package and is ideal for most applications. There is enough capacity in the dc motor controller to generate the output for the 1 input. An enclosure of Cut Tape (CT) is used to package the PMIC. It is capable of handling Transistor Driver dc switching's outputs (s). The supply and operating voltage of the dc control are 7.6V~30V. Worked in a -40°C~85°C TA dc switcher before. This switching controller can switch at Up to 500kHz. The Surface Mount allows it to be used for dc dc regulator in general. Featured in the dcdc regulator is Frequency Control which allows efficient switching control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING REGULATOR. Thare switching converters has a terminal (s) at DUAL . A variety of terminations with 8 of dc switching. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 15V. You can find other relevant dc to dc converter ics by searching "TL2843". The switching converter has a total of 8 pins. The type is a particular Switching Regulator or Controllers of switching converter. Statistically, DC regulator outputs 30V volts. If you are starting a new project, you should note the dc dc regulator's typical output current is 200mA. It is set to 100 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. A frequency of 500kHz is used by the switching controller. A dc switching in a dormant state uses 11mA. You can set the input voltage to 5.5V for nominal working status. Voltage 15V is required for supply. You should not supply more current than 30mA to the controller. With a current supply of 11mA, it runs.
