UC3843D Overview
In the 14-SOIC (0.209, 5.30mm Width) package, the switching controller meets most application requirements. This dc motor controller can be used to generate outputs with 1 numbers. A solid enclosure of Tube surrounds pmic. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sdc controls with 7.6V~30V voltage are supplied and operated. Suitable for working in an dc switcher that has a 0°C~70°C TA. Using this switching controller, it is possible to switch at Up to 500kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. In order to control switching efficiently, the dcdc regulator features 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 terminations with 14 of dc switching. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. DC switcher's input voltageis set to 15V. Input voltage of dc dc voltage regulator must be 8.2V. According to the test statistics, DC regulator outputs 2.5V voltage. The dc to dc regulator is limited to 25V input voltage. As a result, switching converter outputs current to the greatest value possible (1A).
