UC2843D Product Details

UC2843D Overview


It comes in the 14-SOIC (0.154, 3.90mm Width) package, which makes switching controller suitable for most applications. It is sufficient to generate 1 outputs with this dc motor controller. Packaging for the pmic consists of Tube solid enclosures. The program can handle Transistor Driver dc switching's outputs (s). dc control's supply and operating voltages are 12V~28V. Qualified to work in an dc switcher with -40°C~85°C TA. The switching controller can be switched at Up to 500kHz. dc dc regulators can be carried out with Surface Mount. Frequency Control provides dcdc regulator efficient switching control. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. There are a DUAL terminal on the switching converters. Different dc switching's functions can be applied to 14 terminations. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. DC switcher's voltage input of 15V. UC2843 can be searched for other relevant dc to dc converter ics. In total, switching converter has 14 pins. Switching converter type is specifically Switching Regulator or Controllers. Statistically, DC regulator outputs 13.5V volts. In most cases, the output current of the dc dc regulator will be 1A, so note that when you start the project. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 100 %. 450kHz is the frequency of the switching controller. 25V is the nominal working voltage. A controller's current should not exceed 25mA.
