TL3843BDRG4 Overview


As a result of 14-SOIC (0.154, 3.90mm Width) compact design, the switching controller is compatible with most applications. There is sufficient capacity to generate switching controller for outputs 1. Tape & Reel (TR) solid enclosure protects the pmic. Transistor Driver dc switching's outputs (s) can be handled by it. The supply and operating voltage of the dc control are 7.6V~30V. Qualified to work in a 0°C~70°C TA dc switcher. With this switching controller, you can switch at Up to 500kHz. dc dc regulators can be carried out with Surface Mount. The dcdc regulator features Frequency Control for efficient switching control. SWITCHING CONTROLLER analog IC connects the switch converters. DUAL are the position of the terminal of the switching converters. 14 terminations with a variety of function. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. DC switcher's voltage input of 15V. Search for "TL3843" to find other relevant dc to dc converter ics. There are only 14 pins on switching converter. Particularly, switching converter is a type of Switching Regulator or Controllers. The test statistics indicate that DC regulator outputs a voltage of 30V. If you are starting a new project, you should note the dc dc regulator's typical output current is 200mA. Voltage regulator dc to dc is designed to operate at 100 % duty cycle during power-ups and power-downs to ensure reliability. There is 500kHz frequency setting on the switching controller. 5.5V is the nominal working voltage. The supply voltage should be 15V. Current supplied to the controller should not exceed 30mA.
