UC2843AD Overview

It comes in a 14-SOIC (0.154, 3.90mm Width) package, so switching controller can be used for most applications. For outputs of 1, this dc motor controller is suitable. A solid enclosure of Tube surrounds pmic. A total of Transistor Driver dc switching's outputs can be handled by it. 7.6V~30V is the supply voltage and the operating voltage of the dc control. Qualified to work in a -40°C~85°C TA dc switcher. Switching can be done at Up to 500kHz with this switching controller. The Surface Mount allows it to be used for dc dc regulator in general. DCDC regulator is controlled efficiently by Frequency Control. The switch converters are connected to a SWITCHING CONTROLLER analog IC. There are a DUAL terminal on the switching converters. A variety of dc switching's functions can be performed on 14 terminations. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. A search for "UC*84" will reveal other relevant dc to dc converter ics. Pins number 14 of switching converter in total. There is a particular type of Switching Regulator or Controllers in switching converter. This dc dc voltage regulator should be powered by a voltage of 8.2V. Based on the test statistics, DC regulator outputs voltage 15V. It should be noted that the dc to dc regulator only accepts 30V voltage as input voltage. In most cases, the output current of the dc dc regulator will be 200mA, so note that when you start the 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. This Surface Mount makes DC switcher suitable for most prototypes and applications. A frequency of 500kHz is set for the switching controller. An input of 11mA current flow could satisfy the operation of the switching converter .
