UC3874DW-2 Overview


It comes in the 18-SOIC (0.295, 7.50mm Width) package, which makes switching controller suitable for most applications. For 1 outputs, the dc motor controller is appropriate. Tube solid enclosure protects the pmic. It is capable of handling Transistor Driver dc switching's outputs (s). This dc control has a supply voltage and operating voltage of 4.4V~36V. Qualified to work in a 0°C~70°C TA dc switcher. The switching controller can be switched at Up to 300kHz. A generalization of dc dc regulator can be made using Surface Mount. DCDC regulator is controlled efficiently by Soft Start. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. There are a DUAL terminal on the switching converters. A variety of terminations with 18 of dc switching. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. There is a DC switcher's nominal voltage of 12V. Considering the dc to dc regulator can only accept 36V input voltage, it is important to take note of this. The output of this function is the greatest value of 1A.
