UC2843ADG4 Overview


Capsuled in the 14-SOIC (0.154, 3.90mm Width) package, the switching controller suits most application needs. The pmic is packaged in Tube solid enclosure. The program can handle Transistor Driver dc switching's outputs (s). This dc control operates at 7.6V~30V and has a 7.6V~30V supply voltage. Qualified to work in an dc switcher with -40°C~85°C TA. There is a switch at Up to 500kHz that can be used with this controller. The Surface Mount allows it to be used for dc dc regulator in general. Frequency Control is used for efficient switching control in the dcdc regulator. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. switching converters terminal (s) are designed to be at DUAL. Various 14 terminations. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. You can find other relevant dc to dc converter ics by searching "UC2843". 14 pins are present on switching converter. Particularly, switching converter is a type of Switching Regulator or Controllers. DC regulator outputs 15V voltage based on test statistics. normally, the dc dc regulator's output current is 200mA, which you should keep in mind when starting a project. The maximum duty cycle of this voltage regulator dc to dc is set to 100 % to ensure reliability during power-up and power-down. Switching controller operates at 450kHz Hz. A nominal working status is achieved when the input voltage is set to 25V. The supply voltage must be 11V. Current supplied to the controller should not exceed 25mA. This controller switches with 1 phases.
