UC3842NG4 Overview
With a 8-DIP (0.300, 7.62mm) package, the switching controller is suitable for a wide range of applications. 1 outputs can be generated with the dc motor controller. PMIC is packaged in a solid enclosure of Tube. It is capable of handling Transistor Driver dc switching's outputs (s). This dc control has a supply voltage and operating voltage of 12V~28V. Worked in a 0°C~70°C TA dc switcher before. Using this switching controller, it is possible to switch at Up to 500kHz. The Through Hole value makes it suitable for general dc dc regulator. To ensure efficient switching, this dcdc regulator features a Frequency Control. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. A switching converters's terminal (s) sits at the DUAL position. The 8 terminations can be used for a wide range of dc switching. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 15V. Searching "UC3842" will return other relevant dc to dc converter ics. Pins number 8 of switching converter in total. Switching converter type is specifically Switching Regulator or Controllers. Statistically, DC regulator outputs 13.5V volts. The dc dc regulator's usual output current is 200mA, which should be noted down when you start a 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. 25V is the nominal working voltage. In order to ensure proper operation, the controller should not receive more current than 25mA. Input of 11mA current flow would satisfy the operation requirements of the switching converter .
