UC3841Q Product Details

UC3841Q Overview


It comes in the 20-LCC (J-Lead) package, which makes switching controller suitable for most applications. 1 outputs can be generated with the dc motor controller. Packaged in solid enclosures, this pmic has a Tube rating. Transistor Driver dc switching's outputs (s) can be handled by it. The supply and operating voltage of the dc control are 8V~32V. Suitable for work in a 0°C~70°C TA dc switcher. The switching controller is capable of switching at the 500kHz position. A generalization of dc dc regulator can be made using Surface Mount. To ensure efficient switching, this dcdc regulator features a Current Limit, Enable, Frequency Control, Ramp, Reset, Soft Start. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. The switching converters's terminal (s) are designed at QUAD . Various 20 terminations. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. A DC switcher's nominal voltage of 20V is input. Other relevant dc to dc converter ics can be found by searching "UC3841". Particularly, switching converter is a type of Switching Regulator or Controllers. dc dc voltage regulators should have a minimum input voltage of 8V. Voltages 30V are the maximum that the dc to dc regulator will accept. 450kHz is the frequency of the switching controller. In order to satisfy the need, DC to DC voltage regulator has a value of CURRENT MODE OPERATION IS ALSO POSSIBLE. The output value is set to the greatest value of 1A. As long as the dc switching is in a dormant state, it utilizes 4.5mA.
