UC3841DWG4 Overview
As a result of 18-SOIC (0.295, 7.50mm Width) compact design, the switching controller is compatible with most applications. This dc motor controller can be used to generate outputs with 1 numbers. Packaged in solid enclosures, this pmic has a Tube rating. A total of Transistor Driver dc switching's outputs can be handled by it. dc control's supply and operating voltages are 8V~32V. Suitable for a 0°C~70°C TA dc switcher. Using this switching controller, it is possible to switch at 500kHz. dc dc regulator is made easier with Surface Mount. The dcdc regulator features Current Limit, Enable, Frequency Control, Ramp, Reset, Soft Start for efficient switching control. A SWITCHING CONTROLLER analog IC is connected to the switch converters. Switching converters are designed with the terminal (s) at position DUAL . A variety of dc switching's functions can be performed on 18 terminations. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's input voltageis 20V volts. You can find other relevant dc to dc converter ics by searching "UC3841". There are 18 pins on switching converter. In particular, switching converter belongs to the Switching Regulator or Controllers family. As determined by the test statistics, the output voltage of DC regulator is 40V. You should note that the dc dc regulator's usual output current is 400mA. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 95 %. Switching controller operates at 450kHz Hz. Hence, CURRENT MODE OPERATION IS ALSO POSSIBLE is used to better suit the DC to DC voltage regulator's situation. For nominal working status, the input voltage can be set as 30V.
