UCC2891PW Overview


With a 16-TSSOP (0.173, 4.40mm Width) package, the switching controller is suitable for a wide range of applications. 1 outputs are supported by the dc motor controller. Tube is the solid enclosure in which PMIC is packaged. Transistor Driver dc switching's outputs (s) can be handled by it. This dc control operates at 8.5V~16V and has a 8.5V~16V supply voltage. Work well in dc switchers with a -40°C~85°C TA. Switching can be done at 250kHz with this switching controller. A generalization of dc dc regulator can be made using Surface Mount. For efficient switching control, the dcdc regulator features Current Limit, Enable, On Time Control, Ramp, Soft Start. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. Thare switching converters has a terminal (s) at DUAL . The 16 terminations can be used for a wide range of dc switching. 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 12V is input. Other relevant dc to dc converter ics can be found by searching "UCC2891". In total, switching converter has 16 pins. Switching converter is a type of Switching Regulator or Controllers in particular. DC regulator outputs 11.1V voltage according to the test statistics. A starting point for a project is to note down the dc dc regulator's usual output current, which is 150mA. The maximum duty cycle of this voltage regulator dc to dc is set to 73 % to ensure reliability during power-up and power-down. Switching controller operates at a frequency of 1MHz. A circuit should contain 12V in order to ensure the voltage regulator dc to dc runs safely and reliably. Dormant dc switchings use 2mA. 110V is the nominal working voltage. There must be a voltage supply of 12V volts. It is not recommended to supply more current to the controller than 3mA.
