UC3879DWTR Overview


With a 20-SOIC (0.295, 7.50mm Width) package, the switching controller is suitable for a wide range of applications. For outputs of 4, this dc motor controller is suitable. There is a Tape & Reel (TR) solid enclosure around the pmic. A total of Transistor Driver dc switching's outputs can be handled by it. The supply and operating voltage of the dc control are 9V~20V. Suitable for work in a 0°C~70°C TA dc switcher. A switching controller such as this can switch at a value of Up to 300kHz . It is suitable for general dc dc regulator when it is set to Surface Mount. The dcdc regulator features Frequency Control, Ramp, Soft Start for efficient switching control. A SWITCHING CONTROLLER analog IC is connected to the switch converters. There are a terminal (s) on the switching converters that are designed at DUAL. 20 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. The DC switcher's nominal voltage is 12V. You can find other relevant dc to dc converter ics by searching "UC3879". Pins number 20 of switching converter in total. In particular, switching converter belongs to the Switching Regulator or Controllers family. The test statistics indicate that DC regulator outputs a voltage of 2.2V. A starting point for a project is to note down the dc dc regulator's usual output current, which is 10mA. This Surface Mount makes DC switcher suitable for most prototypes and applications. The switching controller works at a frequency of 500kHz. Hence, ALSO HAS CONTROL MODE OF IPK, ALSO HAS CONTROL TECHNIQUE OF RESONANT is used to better suit the DC to DC voltage regulator's situation. It is possible to set the input voltage to 12V for nominal working status.
