UC2843N Product Details
UC2843N Overview
As a result of 8-DIP (0.300, 7.62mm) compact design, the switching controller is compatible with most applications. 1 outputs are supported by the dc motor controller. An enclosure of Tube is used to package the PMIC. The system can process Transistor Driver dc switching's outputs (s). 12V~28V is the supply voltage and the operating voltage of the dc control. Workable in an dc switcher where -40°C~85°C TA is the -40°C~85°C TArm. The switching controller is capable of switching at the Up to 500kHz position. dc dc regulator can be generalized using Through Hole. Switching control is made easier with the dcdc regulator's Frequency Control. 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. There are many different types of terminations for 8. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 15V. A search for "UC2843" will reveal other relevant dc to dc converter ics. 8 pins are present on switching converter. The type is a particular Switching Regulator or Controllers of switching converter. Statistically, the DC regulator outputs 13.5V voltage. It's important to remember that the dc dc regulator's normaloutput current is 1A, so you should note it down when starting a new 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. As DC switcher has a Through Hole, it's suitable for most applications and prototype designs. Switching controller operates at 450kHz Hz. It is possible to set the input voltage as 25V for nominal working statuses. You should not supply more current than 25mA to the controller. 11mA current flow input could be used to operate the switching converter .
