UC2841DW Overview


With its 18-SOIC (0.295, 7.50mm Width) package, the switching controller fits the needs of most applications. 1 outputs are supported by the dc motor controller. Packaging for the pmic consists of Tube solid enclosures. With this function, you can deal with Transistor Driver dc switching's outputs (s). 8V~32V is the supply voltage and the operating voltage of the dc control. A -25°C~85°C TA dc switcher is not a problem. This switching controller can switch at 500kHz. The Surface Mount allows it to be used for dc dc regulator in general. DCDC regulator is controlled efficiently by Current Limit, Enable, Frequency Control, Ramp, Reset, Soft Start. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. Switching converters are designed with the terminal (s) at position DUAL . Various 18 terminations. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. A DC switcher's nominal voltage of 20V is input. You can find other relevant dc to dc converter ics by searching "UC2841". There are a total of 18 pins on switching converter. Switching converter is a type of Switching Regulator or Controllers in particular. Test statistics indicate DC regulator outputs 40V voltage. The dc dc regulator's usual output current is 400mA, which should be noted down when you start a project. It is set to 95 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. Switching controller operates at a frequency of 450kHz. In order to satisfy the need, DC to DC voltage regulator has a value of CURRENT MODE OPERATION IS ALSO POSSIBLE. Input voltage can be set to 30V for nominal working status.
