    Products Detail

    E-UC3843BD1 Overview


    It comes in a 8-SOIC (0.154, 3.90mm Width) package, so switching controller can be used for most applications. This dc motor controller can be used to generate outputs with 1 numbers. Tube is the solid enclosure in which PMIC is packaged. With Transistor Driver dc switching's output (s), it is able to handle it. dc controls with 7.6V~30V voltage are supplied and operated. A 0°C~70°C TA dc switcher is not a problem. A switching controller such as this can switch at a value of 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. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. Thare switching converters has a terminal (s) at DUAL . A variety of 8 terminations are available in dc switching. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. DC switcher's input voltageis 15V volts. UC3843 can be used to locate other relevant dc to dc converter ics. The switching converter has a total of 8 pins. As determined by the test statistics, the output voltage of DC regulator is 5.1V. The dc to dc regulator is limited to 30V input voltage. You should note down the dc dc regulator's usual output current of 1A when you start a project. A duty cycle set at 100 % ensures voltage regulator dc to dc reliability during power-on and power-off. This Surface Mount makes DC switcher suitable for most prototypes and applications. Switching controller operates at a frequency of 250kHz.
