UC3844D8TR Product Details

UC3844D8TR Overview


Capsuled in the 8-SOIC (0.154, 3.90mm Width) package, the switching controller suits most application needs. The dc motor controller is adquate to generate for 1 outputs. The pmic is packaged in Tape & Reel (TR) solid enclosure. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sThe supply and operating voltage of the dc control are 12V~28V. Qualified to work in a 0°C~70°C TA dc switcher. This switching controller can switch at Up to 500kHz. Surface Mount makes it suitable for general dc dc regulator. The dcdc regulator features Frequency Control for efficient switching control. The switch converters are connected to a SWITCHING CONTROLLER analog IC. Terminal (s) of the switching converters are designed at the DUAL position. 8 terminations with a variety of function. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. 15V nominal DC switcher's voltage input. Other relevant dc to dc converter ics can be found by searching "UC3844". Switching converter has a total of 8 pins. Switching converter is a type of Switching Regulator or Controllers in particular. According to the test statistics, DC regulator outputs 13.5V voltage. The dc dc regulator's usual output current is 200mA, which should be noted down when you start a project. To ensure the reliability under power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set as 50 %. The switching controller works at a frequency of 450kHz. For nominal working status, the input voltage can be set as 25V. Current supplied to the controller should not exceed 25mA.
