UC3844BD Overview


It comes in the 14-SOIC (0.154, 3.90mm Width) package, which makes switching controller suitable for most applications. This dc motor controller can be used to generate outputs with 1 numbers. A solid enclosure of Tube surrounds pmic. It is capable of handling Transistor Driver dc switching's outputs (s). This dc control has a supply voltage and operating voltage of 10V~36V. Suitable for a 0°C~70°C TA dc switcher. This switching controller can switch at Up to 500kHz. It is suitable for general dc dc regulator when it is set to Surface Mount. Featured in the dcdc regulator is Frequency Control which allows efficient switching control. A SWITCHING CONTROLLER analog IC is connected to the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. A variety of terminations with 14 of dc switching. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 15V. UC384*B can be searched for other relevant dc to dc converter ics. There are only 14 pins on switching converter. There is a particular type of Switching Regulator or Controllers in switching converter. As determined by the test statistics, the output voltage of DC regulator is 5.1V. The dc to dc regulator can only accept a maximum input voltage of 25V. In most cases, the dc dc regulator's output current is 1A. This information should be noted when you begin working with the component. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 48 %. Having a Surface Mount makes DC switcher suitable for most application and prototype designs. The switching controller works at a frequency of 275kHz. The dc switching utilizes 12mA when it is in a dormant state.
