UC3844AD1 Product Details
UC3844AD1 Overview
With its 8-SOIC (0.154, 3.90mm Width) package, the switching controller fits the needs of most applications. There is sufficient capacity to generate switching controller for outputs 1. PMIC packaging is solid with a Tube enclosure. The program can handle Transistor Driver dc switching's outputs (s). A 10V~30V voltage is supplied to the dc control and used for operating it. Work well in dc switchers with a -40°C~150°C TJ. This switching controller can switch at Up to 500kHz. The Surface Mount value makes it suitable for general dc dc regulator. To ensure efficient switching, this dcdc regulator features a Frequency Control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. There are a DUAL terminal on the switching converters. The 8 terminations can be used for a wide range of dc switching. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. A search for "UC3844" will reveal other relevant dc to dc converter ics. There are a total of 8 pins on switching converter. Particularly, switching converter is a type of Switching Regulator or Controllers. This dc to dc regulator accepts only 30V input voltage at most. This Surface Mount makes DC switcher suitable for most prototypes and applications. 250kHz is the frequency of the switching controller. As a result, switching converter outputs current to the greatest value possible (1A).
