UC3844BNST Product Details

UC3844BNST Overview


With a 8-DIP (0.300, 7.62mm) package, the switching controller is suitable for a wide range of applications. 1 outputs can be generated with the dc motor controller. A solid enclosure of Tube surrounds pmic. A total of Transistor Driver dc switching's outputs can be handled by it. 10V~30V is the operating voltage and supply voltage of the dc control. Worked in a 0°C~70°C TJ dc switcher before. A switching controller such as this can switch at a value of Up to 500kHz . The Through Hole allows it to be used for dc dc regulator in general. Switching control is made easier with the dcdc regulator's Frequency Control. UC3844 can be searched for other relevant dc to dc converter ics. DC regulator's maximum frequency is 500kHz. A temperature 0°C lower than 0°C should be maintained. There should be 70°C more than 70°C degrees Celsius in the machine. This part's supplier dc dc controller package would be 8-Mini DIP.
