TL3843DR Overview
It comes in a 14-SOIC (0.154, 3.90mm Width) package, so switching controller can be used for most applications. This dc motor controller can be used to generate outputs with 1 numbers. An enclosure of Cut Tape (CT) is used to package the PMIC. With this function, you can deal with Transistor Driver dc switching's outputs (s). This dc control operates at 7.6V~30V and has a 7.6V~30V supply voltage. Suitable for working in an dc switcher that has a 0°C~70°C TA. In this switching controller, the switch can be set to 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. A SWITCHING REGULATOR analog IC is connected to the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. 14 terminations with various dc switching's functions. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. 15V nominal DC switcher's voltage input. You can find other relevant dc to dc converter ics by searching "TL3843". There are 14 pins on switching converter. Particularly, switching converter is a type of Switching Regulator or Controllers. Statistically, the DC regulator outputs 30V voltage. In most cases, the dc dc regulator's output current is 200mA. This information should be noted when you begin working with the component. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 100 %. A frequency of 500kHz is used by the switching controller. When the dc switching is dormant, it uses 11mA. A nominal working status is achieved when the input voltage is set to 5.5V. Voltage 15V is required for supply. There should be 30mA more than 30mA amps of current supplied to the controller.
