TL3844BDR Overview
This switching controller fits most application requirements since it is packaged in a 14-SOIC (0.154, 3.90mm Width) package. The dc motor controller is adquate to generate for 1 outputs. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. The system can process Transistor Driver dc switching's outputs (s). This dc control has a supply voltage and operating voltage of 10V~30V. Worked in a 0°C~70°C TA dc switcher before. The switching controller can be switched at Up to 500kHz. The Surface Mount value makes it suitable for general dc dc regulator. DCDC regulator is controlled efficiently by Frequency Control. The switch converters are connected to an analog IC with a SWITCHING REGULATOR output. The switching converters's terminal (s) are designed at DUAL . 14 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. A DC switcher's nominal voltage of 15V is input. In addition to "TL3844", there are other relevant dc to dc converter ics you can find. In total, switching converter has 14 pins. The type is a particular Switching Regulator or Controllers of switching converter. As determined by the test statistics, the output voltage of DC regulator is 30V. A starting point for a project is to note down the dc dc regulator's usual output current, which is 200mA. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 50 %. A frequency of 500kHz is set for the switching controller. You can set the input voltage to 5.5V for nominal working status. Switching controller is necessary to supply a voltage of 15V. Current supplied to the controller should not exceed 30mA.
