UC3845AD8TR Product Details
UC3845AD8TR Overview
It comes in a 8-SOIC (0.154, 3.90mm Width) package, so switching controller can be used for most applications. The dc motor controller is adquate to generate for 1 outputs. Tape & Reel (TR) solid enclosure protects the pmic. With Transistor Driver dc switching's output (s), it is able to handle it. 7.6V~30V is the operating voltage and supply voltage of the dc control. Work well in dc switchers with a 0°C~70°C TA. dc dc regulator can be generalized using Surface Mount. To ensure efficient switching, this dcdc regulator features a Frequency Control. An analog IC SWITCHING CONTROLLER is connected to the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. 8 terminations with various dc switching's functions. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. 15V nominal DC switcher's voltage input. UC3845 can be searched for other relevant dc to dc converter ics. Switching converter has a total of 8 pins. Specially, switching converter corresponds to type Switching Regulator or Controllers. As determined by the test statistics, the output voltage of DC regulator is 15V. A starting point for a project is to note down the dc dc regulator's usual output current, which is 200mA. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 50 %. A frequency of 500kHz is set for the switching controller. You can set the input voltage to 25V for nominal working status. The supply voltage must be 11V. The controller should not be supplied with more current than 25mA.
