TL3844BD-8 Overview


The switching controller fits in the 8-SOIC (0.154, 3.90mm Width) package and is ideal for most applications. It is sufficient to generate 1 outputs with this dc motor controller. Packaged in solid enclosures, this pmic has a Tube rating. The program can handle Transistor Driver dc switching's outputs (s). This dc control has a supply voltage and operating voltage of 10V~30V. A 0°C~70°C TA dc switcher is not a problem. In this switching controller, the switch can be set to Up to 500kHz. Surface Mount makes it suitable for general dc dc regulator. Switching control is made easier with the dcdc regulator's Frequency Control. An analog IC SWITCHING CONTROLLER is connected to the switch converters. The switching converters's terminal (s) are designed at DUAL . Different dc switching's functions can be applied to 8 terminations. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 15V. TL3844 can be used to locate other relevant dc to dc converter ics. The switching converter has a total of 8 pins. There is a particular type of Switching Regulator or Controllers in switching converter. According to the test statistics, DC regulator outputs 30V voltage. It's important to remember that the dc dc regulator's normaloutput current is 200mA, so you should note it down when starting a new project. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 50 %. Switching controller operates at 500kHz Hz. It is possible to set the input voltage as 5.5V for nominal working statuses. The supply voltage should be 15V. You should not supply more current than 30mA to the controller.
