UCC2891DR Overview


Capsuled in the 16-SOIC (0.154, 3.90mm Width) package, the switching controller suits most application needs. There is sufficient capacity to generate switching controller for outputs 1. An enclosure of Tape & Reel (TR) is used to package the PMIC. There are Transistor Driver dc switching's output (s) that it can handle. 8.5V~16V is the operating voltage and supply voltage of the dc control. Qualified to work in a -40°C~85°C TA dc switcher. In this switching controller, the switch can be set to 250kHz. The Surface Mount makes it ideal for general dc dc regulator. 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. Terminal (s) of the switching converters are designed at the DUAL position. A variety of terminations with 16 of dc switching. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. DC switcher's voltage input is 12V. UCC2891 can be used to locate other relevant dc to dc converter ics. There are 16 pins on switching converter. In particular, switching converter belongs to the Switching Regulator or Controllers family. According to the test statistics, DC regulator outputs 11.1V voltage. The dc dc regulator's usual output current is 150mA, which should be noted down when you start a project. It is set to 73 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. There is 1MHz frequency setting on the switching controller. If the user wishes to run the voltage regulator dc to dc in a circuit safely and reliably, they should apply 12V. Input voltage can be set to 110V for nominal working status. Switching controller is necessary to supply a voltage of 12V. You should not supply more current than 3mA to the controller.
