UC3841DW Overview


Capsuled in the 18-SOIC (0.295, 7.50mm Width) package, the switching controller suits most application needs. It is sufficient to generate 1 outputs with this dc motor controller. PMIC packaging is solid with a Tube enclosure. Transistor Driver dc switching's outputs (s) 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. The switching controller is capable of switching at the 500kHz position. dc dc regulators can be carried out with Surface Mount. To provide efficient switching control, Current Limit, Enable, Frequency Control, Ramp, Reset, Soft Start is included in the dcdc regulator. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. switching converters terminal (s) are designed to be at DUAL. 18 terminations with various dc switching's functions. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 20V. You can find other relevant dc to dc converter ics by searching "UC3841". The switching converter has a total of 18 pins. Particularly, switching converter is a type of Switching Regulator or Controllers. Based on the test statistics, DC regulator outputs voltage 40V. A starting point for a project is to note down the dc dc regulator's usual output current, which is 400mA. voltage regulator dc to dcs with a 95 % duty cycle are designed to be reliable when powered on and powered off. Switching controllers operate at 450kHz frequencies. As a result, DC to DC voltage regulator has a value of CURRENT MODE OPERATION IS ALSO POSSIBLE so that the need can be met more directly. Input voltage can be set to 30V for nominal working status.
