UC2843AD8TR Overview


With a 8-SOIC (0.154, 3.90mm Width) package, the switching controller is suitable for a wide range of applications. The dc motor controller is adquate to generate for 1 outputs. There is a Tape & Reel (TR) solid enclosure around the pmic. It is capable of handling Transistor Driver dc switching's outputs (s). The supply and operating voltage of the dc control are 7.6V~30V. Suitable for work in a -40°C~85°C TA dc switcher. This switching controller can switch at Up to 500kHz. dc dc regulator is made easier with Surface Mount. The dcdc regulator features Frequency Control for efficient switching control. An analog IC SWITCHING CONTROLLER is connected to the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. There are many different types of terminations for 8. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. 15V nominal DC switcher's voltage input. You can find other relevant dc to dc converter ics by searching "UC2843". In total, switching converter has 8 pins. Switching converter is a type of Switching Regulator or Controllers in particular. Statistically, the DC regulator outputs 5V voltage. normally, the dc dc regulator's output current is 1A, which you should keep in mind when starting a project. It is set to 100 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. A frequency of 500kHz is set for the switching controller. For nominal working status, the input voltage can be set as 25V. There is a requirement for a 11V supply voltage. Current supplied to the controller should not exceed 25mA.
