UC2845NG4 Overview
In the 8-DIP (0.300, 7.62mm) package, the switching controller meets most application requirements. For 1 outputs, the dc motor controller is appropriate. Tube is the solid enclosure in which PMIC is packaged. It is capable of handling Transistor Driver dc switching's outputs (s). This dc control has a supply voltage and operating voltage of 12V~28V. Suitable for working in an dc switcher that has a -40°C~85°C TA. It can switch at 500kHz. It is suitable for general dc dc regulator when it is set to Through Hole. DCDC regulator is controlled efficiently by Frequency Control. An analog IC SWITCHING CONTROLLER is connected to the switch converters. There are a DUAL terminal on the switching converters. 8 terminations with a variety of function. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. Searching "UC2845" will return other relevant dc to dc converter ics. There are only 8 pins on switching converter. Switching converter is a special type of Switching Regulator or Controllers. Statistically, the DC regulator outputs 13.5V voltage. You should note that the dc dc regulator's usual output current is 200mA. A duty cycle set at 50 % ensures voltage regulator dc to dc reliability during power-on and power-off. There is 450kHz frequency setting on the switching controller. For nominal working status, the input voltage can be set as 25V. There should be 25mA more than 25mA amps of current supplied to the controller. For operation, the switching converter could be satisfied with 11mA current flow input.
