UC2845D8G4 Overview
The switching controller fits in the 8-SOIC (0.154, 3.90mm Width) package and is ideal for most applications. There is sufficient capacity to generate switching controller for outputs 1. An enclosure of Tube is used to package the PMIC. With Transistor Driver dc switching's output (s), it is able to handle it. dc controls with 12V~28V voltage are supplied and operated. 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 Surface Mount. Frequency Control is used for efficient switching control in the dcdc regulator. SWITCHING CONTROLLER analog IC connects the switch converters. Thare switching converters has a terminal (s) at DUAL . There are many different types of terminations for 8. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 15V. You can find other relevant dc to dc converter ics by searching "UC2845". The switching converter has a total of 8 pins. Switching converter type is specifically Switching Regulator or Controllers. A 13.5V voltage of DC regulator was detected in the test statistics. If you are starting a new project, you should note the dc dc regulator's typical output current is 200mA. 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. You can set the input voltage to 25V for nominal working status. There should be 25mA current exceeding 25mA supplied to the controller.
