UC3843AD8 Overview

With a 8-SOIC (0.154, 3.90mm Width) package, the switching controller is suitable for a wide range of applications. It is sufficient to generate 1 outputs with this dc motor controller. PMIC packaging is solid with a Tube enclosure. There are Transistor Driver dc switching's output (s) that it can handle. 7.6V~30V 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. This switching controller can switch at Up to 500kHz. It is suitable for general dc dc regulator when it is set to Surface Mount. DCDC regulator is controlled efficiently by Frequency Control. A SWITCHING CONTROLLER analog IC is connected to the switch converters. There are a terminal (s) on the switching converters that are designed at DUAL. Different dc switching's functions can be applied to 8 terminations. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. The DC switcher's nominal voltage is 15V. You can find other relevant dc to dc converter ics by searching "UC3843". There are a total of 8 pins on switching converter. Switching converter is a special type of Switching Regulator or Controllers. According to the test statistics, DC regulator outputs 5V voltage. It's important to remember that the dc dc regulator's normaloutput current is 200mA, so you should note it down when starting a new project. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 100 %. Switching controller operates at 500kHz Hz. A dc switching in a dormant state uses 11mA. For nominal working status, the input voltage can be set as 25V. There is a requirement for a 11V supply voltage. The controller should not be supplied with more current than 25mA. If there is 11mA current flow input, then the switching converter could operate.
