TL3844DR Overview


Capsuled in the 14-SOIC (0.154, 3.90mm Width) package, the switching controller can be used for a wide range of applications. For outputs of 1, this dc motor controller is suitable. There is a Tape & Reel (TR) solid enclosure around the pmic. It is capable of handling Transistor Driver dc switching's outputs (s). 10V~30V is the supply voltage and the operating voltage of the dc control. Workable in an dc switcher where 0°C~70°C TA is the 0°C~70°C TArm. With this switching controller, you can switch at Up to 500kHz. dc dc regulator can be generalized using Surface Mount. The dcdc regulator features Frequency Control for efficient switching control. The switch converters are connected to a SWITCHING REGULATOR analog IC. There are a DUAL terminal on the switching converters. A variety of 14 terminations are available in dc switching. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's voltage input of 15V. You can find other relevant dc to dc converter ics by searching "TL3844". Pins number 14 of switching converter in total. In particular, switching converter belongs to the Switching Regulator or Controllers family. The test statistics indicate that DC regulator outputs a voltage of 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 used by the switching controller. Input voltage can be set to 5.5V for nominal working status. This voltage controller requires a supply voltage of 15V. In order to ensure proper operation, the controller should not receive more current than 30mA.
