UC3845BNST Overview

With a 8-DIP (0.300, 7.62mm) package, the switching controller is suitable for a wide range of applications. For 1 outputs, the dc motor controller is appropriate. A solid enclosure of Tube surrounds pmic. Transistor Driver dc switching's outputs (s) can be handled by it. This dc control has a supply voltage and operating voltage of 7.6V~30V. Worked in an dc switcher with a -40°C~150°C TJ rating. Switching can be done at 500kHz with this switching controller. The Through Hole value makes it suitable for general dc dc regulator. For efficient switching control, the dcdc regulator features Frequency Control. Search for "UC3845" to find other relevant dc to dc converter ics. DC regulator has a maximum frequency of 500kHz. Ideally, dc regulator should be kept at a temperature of 0°C or higher. The temperature should not exceed 70°C degrees Celsius. The supplier dc dc controller package for this part would be 8-Mini DIP.
