UC3845D8TR Overview
With a 8-SOIC (0.154, 3.90mm Width) package, the switching controller is suitable for a wide range of applications. The dc motor controller is adquate to generate for 1 outputs. Packaging for the pmic consists of Tape & Reel (TR) solid enclosures. It is capable of handling Transistor Driver dc switching's outputs (s). This dc control operates at 12V~28V and has a 12V~28V supply voltage. Worked in a 0°C~70°C TA dc switcher before. This switching controller can switch at 500kHz. Surface Mount makes it suitable for general dc dc regulator. DCDC regulator is controlled efficiently by Frequency Control. SWITCHING CONTROLLER analog IC connects the switch converters. Thare switching converters has a terminal (s) at DUAL . A variety of dc switching's functions can be performed on 8 terminations. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 15V. You can find other relevant dc to dc converter ics by searching "UC3845". Total pins of switching converter are 8. The type is a particular Switching Regulator or Controllers of switching converter. Based on the test statistics, DC regulator outputs voltage 13.5V. It's important to remember that the dc dc regulator's normaloutput current is 200mA, so you should note it down when starting a new project. The duty cycle of the voltage regulator dc to dc can be set to 50 % on power-up or power-down to ensure reliability. The switching controller works at a frequency of 450kHz. Input voltage can be set to 25V for nominal working status. There should be 25mA current exceeding 25mA supplied to the controller.
