UC3843N Overview


The switching controller fits in the 8-DIP (0.300, 7.62mm) package and is ideal for most applications. The dc motor controller is adquate to generate for 1 outputs. There is a Tube solid enclosure around the pmic. The system can process Transistor Driver dc switching's outputs (s). DC control operates at 7.6V~30V volts and has 7.6V~30V supply voltage. Workable in an dc switcher where 0°C~70°C TA is the 0°C~70°C TArm. The switching controller can be switched at Up to 500kHz. The Through Hole allows it to be used for dc dc regulator in general. For efficient switching control, the dcdc regulator features Frequency Control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. A switching converters's terminal (s) sits at the DUAL position. Various 8 terminations. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's input voltageis set to 15V. The minimum input voltage of the dc dc voltage regulator should be 8.2V. According to the test statistics, DC regulator outputs 5V voltage. Considering the dc to dc regulator can only accept 25V input voltage, it is important to take note of this. Whenever the current value is 1A, switching converter outputs the highest possible value.
