UC2847DW Overview


In the 16-SOIC (0.295, 7.50mm Width) package, the switching controller meets most application requirements. 2 outputs can be generated with the dc motor controller. The pmic is packaged in Tube solid enclosure. 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 a -40°C~85°C TA dc switcher before. A switching controller such as this can switch at a value of 500kHz . The Surface Mount value makes it suitable for general dc dc regulator. Current Limit, Enable, Frequency Control, Soft Start is used for efficient switching control in the dcdc regulator. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. The switching converters's terminals (s) are designed at DUAL. Different dc switching's functions can be applied to 16 terminations. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. Other relevant dc to dc converter ics can be found by searching "UC2847". There are only 16 pins on switching converter. The type is a particular Switching Regulator or Controllers of switching converter. The test statistics indicate that DC regulator outputs a voltage of 13.5V. If you start a project, note down the dc dc regulator's usual output current of 500mA. It is set to 50 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. Switching controllers work at 450kHz Hz. 15V is the nominal working voltage.
