UC3843ADM Product Details

UC3843ADM Overview


With its 8-SOIC (0.154, 3.90mm Width) package, the switching controller fits the needs of most applications. For outputs of 1, this dc motor controller is suitable. PMIC is packaged in a solid enclosure of Tube. The system can process Transistor Driver dc switching's outputs (s). Voltages 7.6V~30V are the dc control's supply voltage and operating voltage, respectively. Qualified to work in a 0°C~70°C TA dc switcher. A switching controller such as this can switch at a value of Up to 500kHz . As it has a Surface Mount value, it can be used for general dc dc regulator. Featured in the dcdc regulator is Frequency Control which allows efficient switching control. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. Thare switching converters has a terminal (s) 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. DC switcher's input voltageis 15V volts. UC*84 can be searched for other relevant dc to dc converter ics. There are 8 pins on switching converter. Specifically, switching converter falls under the Switching Regulator or Controllers category. DC regulator outputs 5V voltage according to the test statistics. The dc dc regulator's usual output current is 1A, which should be noted down when you start a project. Voltage regulator dc to dc is designed to operate at 100 % duty cycle during power-ups and power-downs to ensure reliability. This Surface Mount makes DC switcher suitable for most prototypes and applications. 500kHz is the frequency of the switching controller. To operate the voltage regulator dc to dc safely and reliably, users should apply 30V. When the dc switching is dormant, it uses 11mA. A current of 11mA is supplied to it. Components may become damaged if their current exceeds 17mA.
