UCC2891D

UCC2891D Overview

The switching controller fits in the 16-SOIC (0.154, 3.90mm Width) package and is ideal for most applications. This dc motor controller can be used to generate outputs with 1 numbers. An enclosure of Tube is used to package the PMIC. Transistor Driver dc switching's outputs (s) are supported. This dc control operates at 8.5V~16V and has a 8.5V~16V supply voltage. Suitable for work in a -40°C~85°C TA dc switcher. As it has a Surface Mount value, it can be used for general dc dc regulator. Current Limit, Enable, On Time Control, Ramp, Soft Start is used for efficient switching control in the dcdc regulator. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. Switching converters are designed with the terminal (s) at position DUAL . 16 terminations with a variety of function. 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 only 16 pins on switching converter. Switching converter type is specifically Switching Regulator or Controllers. Statistically, the DC regulator outputs 900mV voltage. A starting point for a project is to note down the dc dc regulator's usual output current, which is 150mA. Voltage regulator dc to dc is designed to operate at 73 % duty cycle during power-ups and power-downs to ensure reliability. Switching controllers operate at 250kHz frequencies. To run the voltage regulator dc to dc safely and reliably, users should apply 12V to the voltage regulator dc to dc. The dc switching utilizes 2mA when it is in a dormant state. For nominal working status, the input voltage can be set as 110V. Switching controller is necessary to provide a voltage of 12V. It is important that the controller is supplied with 3mA more than 3mA volts of current. A supply current of 2mA is used to power it.
