UC3845ADWTRG4 Product Details

UC3845ADWTRG4 Overview


As a result of 16-SOIC (0.295, 7.50mm Width) compact design, the switching controller is compatible with most applications. 1 outputs are supported by the dc motor controller. An enclosure of Tape & Reel (TR) is used to package the PMIC. The program can handle Transistor Driver dc switching's outputs (s). A 7.6V~30V voltage is supplied to the dc control and used for operating it. Suitable for work in a 0°C~70°C TA dc switcher. Using this switching controller, it is possible to switch at 500kHz. dc dc regulator can be generalized using Surface Mount. The dcdc regulator features Frequency Control for efficient switching control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. Thare switching converters has a terminal (s) at DUAL . 16 terminations with a variety of function. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 15V. Other relevant dc to dc converter ics can be found by searching "UC3845". Switching converter has a total of 16 pins. There is a particular type of Switching Regulator or Controllers in switching converter. Test statistics indicate DC regulator outputs 15V voltage. You should note down the dc dc regulator's usual output current of 200mA when you start a project. Voltage regulator dc to dc is designed to operate at 50 % duty cycle during power-ups and power-downs to ensure reliability. Switching controllers work at 450kHz Hz. If the user wishes to run the voltage regulator dc to dc in a circuit safely and reliably, they should apply 30V. A nominal working status is achieved when the input voltage is set to 25V.
