UC3845BDG Overview
In the 14-SOIC (0.154, 3.90mm Width) package, the switching controller meets most application requirements. For outputs of 1, this dc motor controller is suitable. PMIC is packaged in a solid enclosure of Tube. With this function, you can deal with Transistor Driver dc switching's outputs (s). A 7.6V~30V voltage is supplied to the dc control and used for operating it. Suitable for working in an dc switcher that has a 0°C~70°C TA. With this switching controller, you can switch at 500kHz. The Surface Mount value makes it suitable for general dc dc regulator. Frequency Control provides dcdc regulator efficient switching control. SWITCHING CONTROLLER analog IC connects the switch converters. There are a DUAL terminal on the switching converters. 14 terminations with various dc switching's functions. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. DC switcher's voltage input of 15V. Search for "UC384*B" to find other relevant dc to dc converter ics. 14 pins are present on switching converter. Specially, switching converter corresponds to type Switching Regulator or Controllers. Test statistics indicate DC regulator outputs 13.4V voltage. Voltages 25V are the maximum that the dc to dc regulator will accept. normally, the dc dc regulator's output current is 200mA, which you should keep in mind when starting a project. The duty cycle of the voltage regulator dc to dc can be set to 48 % on power-up or power-down to ensure reliability. As DC switcher has a Surface Mount, it's suitable for most applications and prototype designs. Switching controller operates at 52kHz Hz. The component might suffer damage if the current exceeds 17mA.
