UC3844D Overview


With its 14-SOIC (0.209, 5.30mm Width) package, the switching controller fits the needs of most applications. For 1 outputs, the dc motor controller is appropriate. PMIC is packaged in a solid enclosure of Tube. The system can process Transistor Driver dc switching's outputs (s). Voltages 10V~30V are the dc control's supply voltage and operating voltage, respectively. Worked in an dc switcher with a 0°C~70°C TA rating. It can switch at Up to 500kHz. dc dc regulator can be generalized using Surface Mount. Frequency Control is used for efficient switching control in the dcdc regulator. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. There are a terminal (s) on the switching converters that are designed at DUAL. A variety of 14 terminations are available in dc switching. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. The DC switcher's nominal voltage is 15V. DC regulator outputs 2.5V voltage according to the test statistics. The dc to dc regulator can only accept 25V input voltage. Whenever the current value is 1A, switching converter outputs the highest possible value.
