UC2843BDG Product Details

UC2843BDG Overview


This switching controller fits most application requirements since it is packaged in a 14-SOIC (0.154, 3.90mm Width) package. There is sufficient capacity to generate switching controller for outputs 1. Packaging for the pmic consists of Tube solid enclosures. There are Transistor Driver dc switching's output (s) that it can handle. The supply and operating voltage of the dc control are 7.6V~30V. Worked in a -25°C~85°C TA dc switcher before. This switching controller can switch at Up to 500kHz. Surface Mount makes it suitable for general dc dc regulator. DCDC regulator is controlled efficiently by Frequency Control. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. A switching converters's terminal (s) sits at the DUAL position. The 14 terminations can be used for a wide range of dc switching. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 15V. Searching "UC284*B" will return other relevant dc to dc converter ics. There are a total of 14 pins on switching converter. Switching converter type is specifically Switching Regulator or Controllers. According to the test statistics, DC regulator outputs 13.4V voltage. It should be fully noted that the dc to dc regulator only accepts 25V input voltage at most. A starting point for a project is to note down the dc dc regulator's usual output current, which is 200mA. It is set to 96 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. In most applications and prototype designs, DC switcher is qualified as a Surface Mount. A frequency of 52kHz is used by the switching controller. There is a possibility that a current higher than 30mA will cause improper operation of the component and possibly damage switching voltage regulators.
