UC2846QTR Overview


Capsuled in the 20-LCC (J-Lead) package, the switching controller suits most application needs. For outputs of 2, this dc motor controller is suitable. Packaging for the pmic consists of Tape & Reel (TR) solid enclosures. Transistor Driver dc switching's outputs (s) can be handled by it. 6.95V~40V is the supply voltage and the operating voltage of the dc control. Worked in an dc switcher with a -40°C~85°C TA rating. In this switching controller, the switch can be set to 500kHz. It is suitable for general dc dc regulator when it is set to Surface Mount. The dcdc regulator features Current Limit, Enable, Frequency Control, Soft Start for efficient switching control. An analog IC SWITCHING CONTROLLER is connected to the switch converters. switching converters terminal (s) are designed to be at QUAD. The 20 terminations can be used for a wide range of dc switching. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. Search for "UC2846" to find other relevant dc to dc converter ics. Pins number 20 of switching converter in total. Switching converter is a special type of Switching Regulator or Controllers. Based on the test statistics, DC regulator outputs voltage 13.5V. The dc dc regulator's usual output current is 500mA, which should be noted down when you start a project. A duty cycle set at 50 % ensures voltage regulator dc to dc reliability during power-on and power-off. Switching controllers operate at 450kHz frequencies. You can set the input voltage to 15V for nominal working status.
