UC3842D8 Overview


Capsuled in the 8-SOIC (0.154, 3.90mm Width) package, the switching controller can be used for a wide range of applications. It is sufficient to generate 1 outputs with this dc motor controller. PMIC is packaged in a solid enclosure of Tube. Transistor Driver dc switching's outputs (s) can be handled by it. 12V~28V is the operating voltage and supply voltage of the dc control. Suitable for working in an dc switcher that has a 0°C~70°C TA. With this switching controller, you can switch at Up to 500kHz. dc dc regulator can be generalized using Surface Mount. DCDC regulator is controlled efficiently by Frequency Control. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. The switching converters's terminal (s) are designed at DUAL . An array of 8 terminations of dc switching. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. DC switcher's input voltageis 15V volts. You can find other relevant dc to dc converter ics by searching "UC3842". The switching converter has a total of 8 pins. Switching converter type is specifically Switching Regulator or Controllers. According to the test statistics, DC regulator outputs 13.5V voltage. A starting point for a project is to note down the dc dc regulator's usual output current, which is 1A. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 100 %. A frequency of 450kHz is used by the switching controller. Input voltage can be set to 25V for nominal working status. The controller should not be supplied with more current than 25mA.
