UC2844DTR Overview


This switching controller fits most application requirements since it is packaged in a 14-SOIC (0.154, 3.90mm Width) package. There is sufficient capacity to generate switching controller for outputs 1. Tape & Reel (TR) is the solid enclosure in which PMIC is packaged. The system can process Transistor Driver dc switching's outputs (s). DC control operates at 12V~28V volts and has 12V~28V supply voltage. Qualified to work in an dc switcher with -40°C~85°C TA. The switching controller can be switched at Up to 500kHz. It is suitable for general dc dc regulator when it is set to Surface Mount. Frequency Control provides dcdc regulator efficient switching control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. Terminal (s) of the switching converters are designed at the DUAL position. Different dc switching's functions can be applied to 14 terminations. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. UC2844 can be used to locate other relevant dc to dc converter ics. 14 pins are on switching converter. There is a particular type of Switching Regulator or Controllers in switching converter. Based on the test statistics, DC regulator outputs voltage 13.5V. In most cases, the output current of the dc dc regulator will be 200mA, so note that when you start the project. As a result of this, the maximum duty cycle of the voltage regulator dc to dc must remain 50 % during power-up and power-down. There is 450kHz frequency setting on the switching controller. A nominal working status is achieved when the input voltage is set to 25V. A controller's current should not exceed 25mA.
