UC3844NG Overview
As a result of 8-DIP (0.300, 7.62mm) compact design, the switching controller is compatible with most applications. The dc motor controller is adquate to generate for 1 outputs. 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's10V~30V is the supply voltage and the operating voltage of the dc control. A 0°C~70°C TA dc switcher is not a problem. Switching can be done at Up to 500kHz with this switching controller. The Through Hole value makes it suitable for general dc dc regulator. To ensure efficient switching, this dcdc regulator features a Frequency Control. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. There are a DUAL terminal on the switching converters. 8 terminations with various dc switching's functions. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's input voltageis set to 15V. UC384* can be searched for other relevant dc to dc converter ics. There are a total of 8 pins on switching converter. Specially, switching converter corresponds to type Switching Regulator or Controllers. Statistically, the DC regulator outputs 5.1V voltage. The dc to dc regulator can only accept 25V input voltage. In most applications and prototype designs, DC switcher is qualified as a Through Hole. A frequency of 275kHz is used by the switching controller. To operate the voltage regulator dc to dc safely and reliably, users should apply 30V. The output of this function is the greatest value of 1A.
