UCC2891DRG4 Overview


This switching controller fits most application requirements since it is packaged in a 16-SOIC (0.154, 3.90mm Width) package. It is sufficient to generate 1 outputs with this dc motor controller. The pmic is packaged in Tape & Reel (TR) solid enclosure. The program can handle Transistor Driver dc switching's outputs (s). The supply and operating voltage of the dc control are 8.5V~16V. A -40°C~85°C TA dc switcher is not a problem. It can switch at 250kHz. The Surface Mount value makes it suitable for general dc dc regulator. For efficient switching control, the dcdc regulator features Current Limit, Enable, On Time Control, Ramp, Soft Start. An analog IC SWITCHING CONTROLLER is connected to the switch converters. A switching converters's terminal (s) sits at the DUAL position. There are many different types of terminations for 16. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. DC switcher's input voltageis set to 12V. Other relevant dc to dc converter ics can be found by searching "UCC2891". There are a total of 16 pins on switching converter. Particularly, switching converter is a type of Switching Regulator or Controllers. Statistically, the DC regulator outputs 11.1V voltage. In most cases, the dc dc regulator's output current is 150mA. This information should be noted when you begin working with the component. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 73 %. Switching controllers operate at 1MHz frequencies. For safe and reliable operation in a circuit, voltage regulator dc to dc is suggested that users apply 12V. Input voltage can be set to 110V for nominal working status. Voltage 12V must be supplied. It is important that the controller is supplied with 3mA more than 3mA volts of current.
