UC2874DW-1 Overview


It comes in the 18-SOIC (0.295, 7.50mm Width) package, which makes switching controller suitable for most applications. It is sufficient to generate 1 outputs with this dc motor controller. Packaging for the pmic consists of Tube solid enclosures. The program can handle Transistor Driver dc switching's outputs (s). This dc control operates at 9V~36V and has a 9V~36V supply voltage. Suitable for working in an dc switcher that has a -25°C~85°C TA. In this switching controller, the switch can be set to Up to 300kHz. dc dc regulator can be generalized using Surface Mount. To provide efficient switching control, Soft Start is included in the dcdc regulator. SWITCHING CONTROLLER analog IC connects the switch converters. Thare switching converters has a terminal (s) at DUAL . An array of 18 terminations 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. UC2874 can be used to locate other relevant dc to dc converter ics. Total pins of switching converter are 18. Switching converter is a type of Switching Regulator or Controllers in particular. Voltage regulator dc to dc is designed to operate at 100 % duty cycle during power-ups and power-downs to ensure reliability. In most applications and prototype designs, DC switcher is qualified as a Surface Mount. DC regulator120kHz has the maximum frequency. A circuit should contain 36V in order to ensure the voltage regulator dc to dc runs safely and reliably. Current is output to the greatest value of 1A. In order to limit the voltage of a dc switcher whose maximum input voltage is 36V, it must be limited by the user. The supply voltage must be 4.5V.
