UC2843AQD8R Overview


As a result of 8-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. Cut Tape (CT) solid enclosure protects the pmic. A total of Transistor Driver dc switching's outputs can be handled by it. This dc control operates at 7.6V~30V and has a 7.6V~30V supply voltage. Suitable for a -40°C~125°C TA dc switcher. This switching controller can switch at Up to 500kHz. dc dc regulators can be carried out with Surface Mount. In order to control switching efficiently, the dcdc regulator features Frequency Control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. Switching converters are designed with the terminal (s) at position DUAL . Different dc switching's functions can be applied to 8 terminations. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. DC switcher's voltage input of 15V. In addition to "UC2843", there are other relevant dc to dc converter ics you can find. Total pins of switching converter are 8. Particularly, switching converter is a type of Switching Regulator or Controllers. According to the test statistics, DC regulator outputs 15V voltage. This dc to dc regulator accepts only 25V input voltage at most. If you are starting a new project, you should note the dc dc regulator's typical output current is 200mA. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 100 %. Because of DC switcher's Surface Mount, it is suitable for most prototype designs and applications. Switching controller operates at a frequency of 500kHz. Automotive, AEC-Q100 is a series of dc to dc voltage regulator. As long as the dc switching is in a dormant state, it utilizes 11mA.
