UC2843D8TRG4 Product Details
UC2843D8TRG4 Overview
It comes in the 8-SOIC (0.154, 3.90mm Width) package, which makes switching controller suitable for most applications. 1 outputs can be generated with the dc motor controller. The pmic is packaged in Tape & Reel (TR) solid enclosure. Transistor Driver dc switching's outputs (s) can be handled by it. DC control operates at 12V~28V volts and has 12V~28V supply voltage. A -40°C~85°C TA dc switcher is not a problem. The switching controller is capable of switching at the Up to 500kHz position. A generalization of dc dc regulator can be made using Surface Mount. 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 . A variety of terminations with 8 of dc switching. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. Searching "UC2843" will return other relevant dc to dc converter ics. Switching converter has a total of 8 pins. The type is a particular Switching Regulator or Controllers of switching converter. According to the test statistics, DC regulator outputs 13.5V voltage. It's important to remember that the dc dc regulator's normaloutput current is 200mA, so you should note it down when starting a new project. The duty cycle of the voltage regulator dc to dc can be set to 100 % on power-up or power-down to ensure reliability. Switching controller operates at a frequency of 450kHz. 25V is the nominal working voltage. In order to ensure proper operation, the controller should not receive more current than 25mA.
