UC3843BD1 Overview
The switching controller fits in the 8-SOIC (0.154, 3.90mm Width) package and is ideal for most applications. For outputs of 1, this dc motor controller is suitable. Tube is the solid enclosure in which PMIC is packaged. It is capable of handling Transistor Driver dc switching's outputs (s). The supply and operating voltage of the dc control are 7.6V~30V. Qualified to work in an dc switcher with 0°C~70°C TA. 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. In order to control switching efficiently, the dcdc regulator features Frequency Control. A SWITCHING CONTROLLER analog IC is connected to the switch converters. Thare switching converters has a terminal (s) at DUAL . A variety of terminations with 8 of dc switching. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 15V. At most, the dc to dc regulator accepts 25V input voltage. The output of this function is the greatest value of 1A.
