TL3843BDR Overview


As a result of 14-SOIC (0.154, 3.90mm Width) compact design, the switching controller is compatible with most applications. The dc motor controller is adquate to generate for 1 outputs. PMIC is packaged in a solid enclosure of Tape & Reel (TR). With this function, you can deal with Transistor Driver dc switching's outputs (s). DC control operates at 7.6V~30V volts and has 7.6V~30V supply voltage. Qualified to work in a 0°C~70°C TA dc switcher. The switching controller can be switched at Up to 500kHz. dc dc regulator is made easier with Surface Mount. For efficient switching control, the dcdc regulator features Frequency Control. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. There are a terminal (s) on the switching converters that are designed at DUAL. A variety of dc switching's functions can be performed on 14 terminations. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. TL3843 can be used to locate other relevant dc to dc converter ics. There are 14 pins on switching converter. Particularly, switching converter is a type of Switching Regulator or Controllers. A 30V voltage of DC regulator was detected in the test statistics. If you start a project, note down the dc dc regulator's usual output current of 200mA. It is set to 100 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. Switching controller operates at 500kHz Hz. A nominal working status is achieved when the input voltage is set to 5.5V. There must be a voltage supply of 15V volts. There should be 30mA more than 30mA amps of current supplied to the controller.
