UC2844N Product Details
UC2844N Overview
It comes in the 8-DIP (0.300, 7.62mm) package, which makes switching controller suitable for most applications. 1 outputs are supported by the dc motor controller. PMIC packaging is solid with a Tube enclosure. Transistor Driver dc switching's outputs (s) are supported. The supply and operating voltage of the dc control are 12V~28V. A -40°C~85°C TA dc switcher is not a problem. This switching controller can switch at Up to 500kHz. dc dc regulator can be generalized using Through Hole. Frequency Control provides dcdc regulator efficient switching control. The switch converters are connected to a SWITCHING CONTROLLER analog IC. Switching converters are designed with the terminal (s) at position DUAL . An array of 8 terminations of dc switching. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 15V. UC2844 can be used to locate other relevant dc to dc converter ics. In total, switching converter has 8 pins. There is a particular type of Switching Regulator or Controllers in switching converter. DC regulator outputs 13.5V 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 duty cycle of the voltage regulator dc to dc can be set to 50 % on power-up or power-down to ensure reliability. 500kHz is the frequency of the switching controller. 25V is the nominal working voltage. It is not recommended to supply more current to the controller than 25mA. An input flow rate of 11mA could satisfy the switching converter 's operation requirements.
