UC3844AM Overview


As a result of 8-DIP (0.300, 7.62mm) compact design, the switching controller is compatible with most applications. 1 outputs are supported by the dc motor controller. PMIC is packaged in a solid enclosure of Tube. Transistor Driver dc switching's outputs (s) are supported. This dc control has a supply voltage and operating voltage of 10V~30V. Qualified to work in an dc switcher with 0°C~70°C TA. The switching controller can be switched at Up to 500kHz. A generalization of dc dc regulator can be made using Through Hole. For efficient switching control, the dcdc regulator features Frequency Control. A SWITCHING CONTROLLER analog IC is connected to the switch converters. There are a terminal (s) on the switching converters that are designed at DUAL. A variety of 8 terminations are available in dc switching. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. 15V nominal DC switcher's voltage input. You can find other relevant dc to dc converter ics by searching "UC*84". Total pins of switching converter are 8. Switching converter type is specifically Switching Regulator or Controllers. This dc to dc regulator accepts only 30V input voltage at most. The duty cycle of the voltage regulator dc to dc can be set to 50 % on power-up or power-down to ensure reliability. In most applications and prototypes, DC switcher's Through Hole makes it suitable. A frequency of 500kHz is set for the switching controller. The output value is set to the greatest value of 1A. When the dc switching is dormant, it uses 11mA.
