UC3844N Overview


With a 8-DIP (0.300, 7.62mm) package, the switching controller is suitable for a wide range of applications. 1 outputs can be generated with the dc motor controller. Packaging for the pmic consists of Tube solid enclosures. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sThis dc control operates at 10V~30V and has a 10V~30V supply voltage. Suitable for working in an dc switcher that has a 0°C~70°C TA. The switching controller is capable of switching at the Up to 500kHz position. dc dc regulator is made easier with Through Hole. DCDC regulator is controlled efficiently by Frequency Control. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. Switching converters are designed with the terminal (s) at position DUAL . 8 terminations with various dc switching's functions. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. UC384* can be searched for other relevant dc to dc converter ics. 8 pins are on switching converter. In particular, switching converter belongs to the Switching Regulator or Controllers family. According to the test statistics, DC regulator outputs 5.1V voltage. The dc to dc regulator can only accept 25V input voltage. In most cases, the dc dc regulator's output current is 1A. This information should be noted when you begin working with the component. It is set to 50 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. As DC switcher has a Through Hole, it's suitable for most applications and prototype designs. A frequency of 275kHz is set for the switching controller. There is a 17mA volt supply current. There is a nominal current supply of 17mA for this the controllers dc.
