UC3843BD1 Overview
The switching controller fits in the 8-SOIC (0.154, 3.90mm Width) package and is ideal for most applications. There is a Tube solid enclosure around the pmic. A total of Transistor Driver dc switching's outputs can be handled by it. dc control's supply and operating voltages are 7.6V~30V. A 0°C~70°C TJ dc switcher is not a problem. In this switching controller, the switch can be set to Up to 500kHz. The Surface Mount value makes it suitable for general dc dc regulator. The dcdc regulator features Frequency Control for efficient switching control. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. A switching converters's terminal (s) sits at the DUAL position. The 8 terminations can be used for a wide range of dc switching. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. DC switcher's voltage input of 15V. In addition to "UC3843", there are other relevant dc to dc converter ics you can find. 8 pins are present on switching converter. In particular, switching converter is a type of Switching Regulator or Controllers. According to the test statistics, DC regulator outputs 5.1V voltage. This dc to dc regulator accepts only 30V input voltage at most. 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. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 100 %. In most applications and prototype designs, DC switcher is qualified as a Surface Mount. The switching controller works at a frequency of 500kHz. This controller contains 1 phases.
