UC3845ADM Product Details

UC3845ADM Overview


As a result of 8-SOIC (0.154, 3.90mm Width) compact design, the switching controller is compatible with most applications. There is sufficient capacity to generate switching controller for outputs 1. There is a Tube solid enclosure around the pmic. Transistor Driver dc switching's outputs (s) can be handled by it. dc controls with 7.6V~30V voltage are supplied and operated. Worked in a 0°C~70°C TA dc switcher before. The Surface Mount makes it ideal for general dc dc regulator. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. The switching converters's terminals (s) are designed at DUAL. A variety of 8 terminations are available in dc switching. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. There is a DC switcher's nominal voltage of 15V. In addition to "UC*84", there are other relevant dc to dc converter ics you can find. In total, switching converter has 8 pins. Switching converter is a type of Switching Regulator or Controllers in particular. The dc to dc regulator can only accept 30V input voltage. A duty cycle set at 50 % ensures voltage regulator dc to dc reliability during power-on and power-off. Having a Surface Mount makes DC switcher suitable for most application and prototype designs. A frequency of 500kHz is used by the switching controller. The output value is set to the greatest value of 1A. DC switchings that are dormant use 11mA.
