E-UC3842BD1 Overview


With its 8-SOIC (0.154, 3.90mm Width) package, the switching controller fits the needs of most applications. There is enough capacity in the dc motor controller to generate the output for the 1 input. There is a Tube solid enclosure around the pmic. With Transistor Driver dc switching's output (s), it is able to handle it. The supply and operating voltage of the dc control are 10V~30V. Qualified to work in a 0°C~70°C TA dc switcher. There is a switch at Up to 500kHz that can be used with this controller. Surface Mount makes it suitable for general dc dc regulator. DCDC regulator is controlled efficiently by Frequency Control. An analog IC SWITCHING CONTROLLER is connected to the switch converters. There are a terminal (s) on the switching converters that are designed at DUAL. A variety of 8 terminations are available in dc switching. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. 15V nominal DC switcher's voltage input. Search for "UC3842" to find other relevant dc to dc converter ics. There are 8 pins on switching converter. According to the test statistics, DC regulator outputs 5.1V voltage. The dc dc regulator's usual output current is 1A, which should be noted down when you start a project. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 100 %. The Surface Mount makes DC switcher suitable for most applications and prototypes. 250kHz is the frequency of the switching controller. When running the voltage regulator dc to dc in a circuit, users should apply 30V to ensure safety and reliability.
