UC3845D Overview


Capsuled in the 14-SOIC (0.154, 3.90mm Width) package, the switching controller suits most application needs. There is sufficient capacity to generate switching controller for outputs 1. Packaging for the pmic consists of Tube solid enclosures. The system can process Transistor Driver dc switching's outputs (s). A 7.6V~30V voltage is supplied to the dc control and used for operating it. Worked in a 0°C~70°C TA dc switcher before. Using this switching controller, it is possible to switch at 500kHz. The Surface Mount allows it to be used for dc dc regulator in general. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. There are a DUAL terminal on the switching converters. The 14 terminations can be used for a wide range of dc switching. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. 15V nominal DC switcher's voltage input. This dc dc voltage regulator should be powered by a voltage of 8.2V. As determined by the test statistics, the output voltage of DC regulator is 2.5V. The dc to dc regulator can only accept a maximum input voltage of 25V. The output value is set to the greatest value of 1A.
