UC3845AD Product Details

UC3845AD Overview


It comes in a SOIC package, so switching controller can be used for most applications. 1 outputs can be generated with the dc motor controller. Tube is the solid enclosure in which PMIC is packaged. The program can handle 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. It is suitable for general dc dc regulator when it is set to Surface Mount. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. There are a DUAL terminal on the switching converters. An array of 14 terminations of dc switching. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. Other relevant dc to dc converter ics can be found by searching "UC*84". Switching converter has a total of 14 pins. Switching converter is a special type of Switching Regulator or Controllers. An input voltage of 8.2V is the minimum required for the dc dc voltage regulator. The test statistics indicate that DC regulator outputs a voltage of 5.1V. At most, the dc to dc regulator accepts 30V input voltage. In most cases, the dc dc regulator's output current is 200mA. This information should be noted when you begin working with the component. voltage regulator dc to dcs with a 50 % duty cycle are designed to be reliable when powered on and powered off. Having a Surface Mount makes DC switcher ideal for most prototype and application designs. Switching controllers work at 500kHz Hz. The dc switching utilizes 11mA when it is in a dormant state. The supplier dc dc controller package for this part would be 14-SOIC. If the current flow input is 11mA, the switching converter could operate.
