TL3844DG4-8 Overview
With a 8-SOIC (0.154, 3.90mm Width) package, the switching controller is suitable for a wide range of applications. This dc motor controller can be used to generate outputs with 1 numbers. Tube solid enclosure protects the pmic. The system can process Transistor Driver dc switching's outputs (s). 10V~30V is the operating voltage and supply voltage of the dc control. Worked in an dc switcher with a 0°C~70°C TA rating. The switching controller is capable of switching at the Up to 500kHz position. As it has a Surface Mount value, it can be used for general dc dc regulator. Frequency Control provides dcdc regulator efficient switching control. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. There are a terminal (s) on the switching converters that are designed at DUAL. 8 terminations with various dc switching's functions. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. In addition to "TL3844", there are other relevant dc to dc converter ics you can find. There are only 8 pins on switching converter. Specially, switching converter corresponds to type Switching Regulator or Controllers. Based on the test statistics, DC regulator outputs voltage 30V. In most cases, the output current of the dc dc regulator will be 200mA, so note that when you start the project. As a result of this, the maximum duty cycle of the voltage regulator dc to dc must remain 50 % during power-up and power-down. A frequency of 500kHz is set for the switching controller. It is possible to set the input voltage to 5.5V for nominal working status.
