UC3844BVN Overview


Capsuled in the 8-DIP (0.300, 7.62mm) package, the switching controller can be used for a wide range of applications. There is sufficient capacity to generate switching controller for outputs 1. Packaged in solid enclosures, this pmic has a Tube rating. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sVoltages 10V~36V are the dc control's supply voltage and operating voltage, respectively. Qualified to work in an dc switcher with -40°C~105°C TA. There is a switch at Up to 500kHz that can be used with this controller. The Through Hole value makes it suitable 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. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. The DC switcher's nominal voltage is 15V. In addition to "UC384*B", there are other relevant dc to dc converter ics you can find. Total pins of switching converter are 8. Particularly, switching converter is a type of Switching Regulator or Controllers. According to the test statistics, DC regulator outputs 5.1V voltage. It should be fully noted that the dc to dc regulator only accepts 25V input voltage at most. normally, the dc dc regulator's output current is 1A, which you should keep in mind when starting a project. As a result of this, the maximum duty cycle of the voltage regulator dc to dc must remain 48 % during power-up and power-down. In most applications and prototype designs, DC switcher is qualified as a Through Hole. Switching controllers operate at 275kHz frequencies. To operate the voltage regulator dc to dc safely and reliably, users should apply 30V. During dormancy, the dc switching uses 12mA.
