UC2845N 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. PMIC packaging is solid with a Tube enclosure. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching's12V~28V is the supply voltage and the operating voltage of the dc control. Suitable for work in a -40°C~85°C TA dc switcher. A generalization of dc dc regulator can be made using Through Hole. DCDC regulator is controlled efficiently by Frequency Control. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. Thare switching converters has a terminal (s) at DUAL . There are many different types of terminations for 8. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. DC switcher's input voltageis set to 15V. Searching "UC2845" will return other relevant dc to dc converter ics. In total, switching converter has 8 pins. Switching converter type is specifically Switching Regulator or Controllers. Based on the test statistics, DC regulator outputs voltage 13.5V. In most cases, the output current of the dc dc regulator will be 1A, so note that when you start the project. To ensure the reliability under power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set as 50 %. The switching controller works at a frequency of 500kHz. It is possible to set the input voltage to 25V for nominal working status. There should be 25mA current exceeding 25mA supplied to the controller.
