UCC2891DG4 Overview

With its 16-SOIC (0.154, 3.90mm Width) package, the switching controller fits the needs of most applications. There is sufficient capacity to generate switching controller for outputs 1. Tube is the solid enclosure in which PMIC is packaged. A total of Transistor Driver dc switching's outputs can be handled by it. dc controls with 8.5V~16V voltage are supplied and operated. Workable in an dc switcher where -40°C~85°C TA is the -40°C~85°C TArm. The switching controller can be switched at 250kHz. dc dc regulator is made easier with Surface Mount. Featured in the dcdc regulator is Current Limit, Enable, On Time Control, Ramp, Soft Start which allows efficient switching control. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. The switching converters's terminals (s) are designed at DUAL. The 16 terminations can be used for a wide range of dc switching. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 12V. Search for "UCC2891" to find 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. The test statistics indicate that DC regulator outputs a voltage of 11.1V. The dc dc regulator's usual output current is 150mA, which should be noted down when you start a project. Voltage regulator dc to dc is designed to operate at 73 % duty cycle during power-ups and power-downs to ensure reliability. A frequency of 1MHz is set for the switching controller. In order for the voltage regulator dc to dc to perform safely and reliably in a circuit, users are advised to apply 12V. For nominal working status, the input voltage can be set as 110V. Switching controller is necessary to supply a voltage of 12V. 3mA more than 3mA current should be supplied to the controller.
