TL2843DR Overview


With its 14-SOIC (0.154, 3.90mm Width) package, the switching controller fits the needs of most applications. It is sufficient to generate 1 outputs with this dc motor controller. An enclosure of Tape & Reel (TR) is used to package the PMIC. A total of Transistor Driver dc switching's outputs can be handled by it. Voltages 7.6V~30V are the dc control's supply voltage and operating voltage, respectively. Qualified to work in a -40°C~85°C TA dc switcher. This switching controller can switch at Up to 500kHz. Surface Mount makes it suitable for general dc dc regulator. In order to control switching efficiently, the dcdc regulator features Frequency Control. SWITCHING REGULATOR analog IC connects the switch converters. The switching converters's terminals (s) are designed at DUAL. 14 terminations with a variety of function. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's input voltageis set to 15V. TL2843 can be searched for other relevant dc to dc converter ics. Switching converter has a total of 14 pins. There is a particular type of Switching Regulator or Controllers in switching converter. Statistically, the DC regulator outputs 30V voltage. You should note that the dc dc regulator's usual output current is 200mA. It is set to 100 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. Switching controllers operate at 500kHz frequencies. DC switchings that are dormant use 11mA. 5.5V is the nominal working voltage. This voltage controller requires a supply voltage of 15V. There should be 30mA more than 30mA amps of current supplied to the controller.
