UC3844DX Overview
The switching controller fits in the 14-SOIC (0.209, 5.30mm Width) package and is ideal for most applications. It is sufficient to generate 1 outputs with this dc motor controller. There is a Tape & Reel (TR) solid enclosure around the pmic. A total of Transistor Driver dc switching's outputs can be handled by it. This dc control has a supply voltage and operating voltage of 10V~30V. A 0°C~70°C TA dc switcher is not a problem. It can switch at Up to 500kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. DCDC regulator is controlled efficiently by Frequency Control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. switching converters terminal (s) are designed to be at DUAL. A variety of terminations with 14 of dc switching. 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. The dc to dc regulator can only accept a maximum input voltage of 30V. The output value is set to the greatest value of 1A.
