UC3842N Overview
In the 8-DIP (0.300, 7.62mm) package, the switching controller meets most application requirements. The dc motor controller is adquate to generate for 1 outputs. The pmic is packaged in Tube solid enclosure. It is capable of handling Transistor Driver dc switching's outputs (s). 12V~28V is the supply voltage and the operating voltage of the dc control. Work well in dc switchers with a 0°C~70°C TA. With this switching controller, you can switch at Up to 500kHz. dc dc regulators can be carried out with Through Hole. Frequency Control is used for efficient switching control in the dcdc regulator. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. Thare switching converters has a terminal (s) at DUAL . There are many different types of terminations for 8. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. DC switcher's input voltageis 15V volts. Other relevant dc to dc converter ics can be found by searching "UC3842". There are only 8 pins on switching converter. Specially, switching converter corresponds to type Switching Regulator or Controllers. As determined by the test statistics, the output voltage of DC regulator is 13.5V. It's important to remember that the dc dc regulator's normaloutput current is 1A, so you should note it down when starting a new project. The maximum duty cycle of this voltage regulator dc to dc is set to 100 % to ensure reliability during power-up and power-down. 450kHz is the frequency of the switching controller. Input voltage can be set to 30V for nominal working status. A controller's current should not exceed 25mA.
