TL3843DR-8 Overview


With its 8-SOIC (0.154, 3.90mm Width) package, the switching controller fits the needs of most applications. 1 outputs can be generated with the dc motor controller. Cut Tape (CT) is the solid enclosure in which PMIC is packaged. With Transistor Driver dc switching's output (s), it is able to handle it. dc controls with 7.6V~30V voltage are supplied and operated. A 0°C~70°C TA dc switcher is not a problem. With this switching controller, you can switch at Up to 500kHz. The Surface Mount allows it to be used for dc dc regulator in general. The dcdc regulator features Frequency Control for efficient switching control. The switch converters are connected to an analog IC with a SWITCHING REGULATOR output. Thare switching converters has a terminal (s) at DUAL . Various 8 terminations. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. DC switcher's input voltageis 15V volts. You can find other relevant dc to dc converter ics by searching "TL3843". The switching converter has a total of 8 pins. Specially, switching converter corresponds to type Switching Regulator or Controllers. DC regulator outputs 30V voltage according to the test statistics. In most cases, the dc dc regulator's output current is 200mA. This information should be noted when you begin working with the component. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 97 %. Switching controllers operate at 500kHz frequencies. In dormant mode, 11mA is used. It is possible to set the input voltage as 5.5V for nominal working statuses. The supply voltage should be 15V. It is not recommended to supply more current to the controller than 30mA.
