UCC2891PWR Overview

In the 16-TSSOP (0.173, 4.40mm Width) package, the switching controller meets most application requirements. The dc motor controller is adquate to generate for 1 outputs. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. A total of Transistor Driver dc switching's outputs can be handled by it. DC control operates at 8.5V~16V volts and has 8.5V~16V supply voltage. Work well in dc switchers with a -40°C~85°C TA. Using this switching controller, it is possible to switch at 250kHz. A generalization of dc dc regulator can be made using Surface Mount. Featured in the dcdc regulator is Current Limit, Enable, On Time Control, Ramp, Soft Start which allows efficient switching control. SWITCHING CONTROLLER analog IC connects the switch converters. There are a DUAL terminal on the switching converters. 16 terminations with a variety of function. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 12V. Search for "UCC2891" to find other relevant dc to dc converter ics. 16 pins are present on switching converter. In particular, switching converter belongs to the Switching Regulator or Controllers family. DC regulator outputs 11.1V voltage according to the test statistics. normally, the dc dc regulator's output current is 150mA, which you should keep in mind when starting a project. Voltage regulator dc to dc is designed to operate at 73 % duty cycle during power-ups and power-downs to ensure reliability. 1MHz is the frequency of the switching controller. When running the voltage regulator dc to dc in a circuit, users should apply 12V to ensure safety and reliability. It is possible to set the input voltage to 110V for nominal working status. Switching controller is necessary to provide a voltage of 12V. There should be 3mA more than 3mA amps of current supplied to the controller.
