UC3845ADTRG4 Overview


It comes in the 14-SOIC (0.154, 3.90mm Width) package, which makes switching controller suitable for most applications. This dc motor controller can be used to generate outputs with 1 numbers. Tape & Reel (TR) solid enclosure protects the pmic. Transistor Driver dc switching's outputs (s) are supported. This dc control has a supply voltage and operating voltage of 7.6V~30V. Work well in dc switchers with a 0°C~70°C TA. Using this switching controller, it is possible to switch at 500kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. Frequency Control provides dcdc regulator efficient switching control. A SWITCHING CONTROLLER analog IC is connected to the switch converters. Thare switching converters has a terminal (s) at DUAL . Various 14 terminations. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 15V. Other relevant dc to dc converter ics can be found by searching "UC3845". Total pins of switching converter are 14. Specially, switching converter corresponds to type Switching Regulator or Controllers. Based on the test statistics, DC regulator outputs voltage 15V. In most cases, the dc dc regulator's output current is 200mA. This information should be noted when you begin working with the component. It is set to 50 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. A frequency of 450kHz is set for the switching controller. A nominal working status is achieved when the input voltage is set to 25V. There must be a voltage supply of 11V volts. Current supplied to the controller should not exceed 25mA.
