E-UC2845BD1 Overview


The switching controller fits in the 8-SOIC (0.154, 3.90mm Width) package and is ideal for most applications. 1 outputs can be generated with the dc motor controller. PMIC is packaged in a solid enclosure of Tube. A total of Transistor Driver dc switching's outputs can be handled by it. 7.6V~30V is the supply voltage and the operating voltage of the dc control. Qualified to work in an dc switcher with -25°C~85°C TA. The switching controller can be switched at Up to 500kHz. The Surface Mount value makes it suitable for general dc dc regulator. To provide efficient switching control, Frequency Control is included in the dcdc regulator. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. The switching converters's terminals (s) are designed at DUAL. 8 terminations with a variety of function. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. Searching "UC2845" will return other relevant dc to dc converter ics. dc dc voltage regulators should have a minimum input voltage of 8.2V. Considering the dc to dc regulator can only accept 30V input voltage, it is important to take note of this. Switching converter outputs current to the greatest value of 1A.
