UC3842AD8TRG4 Overview


With a 8-SOIC (0.154, 3.90mm Width) package, the switching controller is suitable for a wide range of applications. 1 outputs are supported by the dc motor controller. PMIC packaging is solid with a Tape & Reel (TR) enclosure. There are Transistor Driver dc switching's output (s) that it can handle. dc control's supply and operating voltages are 10V~30V. Qualified to work in a 0°C~70°C TA dc switcher. This switching controller can switch at Up to 500kHz. The Surface Mount makes it ideal for general dc dc regulator. Frequency Control provides dcdc regulator efficient switching control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. A switching converters's terminal (s) sits at the DUAL position. A variety of dc switching's functions can be performed on 8 terminations. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's voltage input of 15V. In addition to "UC3842", there are other relevant dc to dc converter ics you can find. Total pins of switching converter are 8. In particular, switching converter is a type of Switching Regulator or Controllers. A 15V voltage of DC regulator was detected in the test statistics. 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 100 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. 450kHz is the frequency of the switching controller. For nominal working status, the input voltage can be set as 25V. There is a requirement for a 11V supply voltage. 25mA more than 25mA current should be supplied to the controller.
