UC2844D Overview
With a 14-SOIC (0.154, 3.90mm Width) package, the switching controller is suitable for a wide range of applications. This dc motor controller can be used to generate outputs with 1 numbers. Packaging for the pmic consists of Tube solid enclosures. The system can process Transistor Driver dc switching's outputs (s). DC control operates at 12V~28V volts and has 12V~28V supply voltage. Worked in a -40°C~85°C TA dc switcher before. This switching controller can switch at Up to 500kHz. dc dc regulators can be carried out with Surface Mount. To ensure efficient switching, this dcdc regulator features a Frequency Control. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. switching converters terminal (s) are designed to be at DUAL. A variety of 14 terminations are available in dc switching. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. DC switcher's input voltageis set to 15V. Based on the test statistics, DC regulator outputs voltage 2.5V. The dc to dc regulator can only accept a maximum input voltage of 25V. Switching converter outputs current to the greatest value of 1A.
