TL3844D Overview
With a 14-SOIC (0.154, 3.90mm Width) package, the switching controller is suitable for a wide range of applications. dc motor controller is suitable for 1 output generation. PMIC is packaged in a solid enclosure of Tube. A total of Transistor Driver dc switching's outputs can be handled by it. dc controls with 10V~30V voltage are supplied and operated. Worked in an dc switcher with a 0°C~70°C TA rating. It can switch at Up to 500kHz. dc dc regulator is made easier with Surface Mount. To provide efficient switching control, Frequency Control is included in the dcdc regulator. A SWITCHING REGULATOR analog integrated circuit is connected to the switch converters. The switching converters's terminal (s) are designed at DUAL . A variety of dc switching's functions can be performed on 14 terminations. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. DC switcher's input voltageis 15V volts. A search for "TL3844" will reveal other relevant dc to dc converter ics. 14 pins are present on switching converter. Specially, switching converter corresponds to type Switching Regulator or Controllers. DC regulator outputs 30V voltage based on 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 50 %. Switching controller operates at a frequency of 500kHz. 5.5V is the nominal working voltage. Switching controller is necessary to provide a voltage of 15V. There should be 30mA current exceeding 30mA supplied to the controller.
