14 Terminals 12V~28V 14-Pin UC2845 DC to DC converter IC SWITCHING CONTROLLER 1 Outputs Transistor Driver
UC2845D Overview
With its 14-SOIC (0.154, 3.90mm Width) package, the switching controller fits the needs of most applications. For outputs of 1, this dc motor controller is suitable. Tube solid enclosure protects the pmic. 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 -40°C~85°C TA dc switcher before. The Surface Mount allows it to be used for dc dc regulator in general. In order to control switching efficiently, the dcdc regulator features Frequency Control. SWITCHING CONTROLLER analog IC connects the switch converters. Switching converters are designed with the terminal (s) at position DUAL . The 14 terminations can be used for a wide range of dc switching. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. Searching "UC2845" will return other relevant dc to dc converter ics. 14 pins are on switching converter. Based on the test statistics, DC regulator outputs voltage 13.5V. If you are starting a new project, you should note the dc dc regulator's typical output current is 200mA. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 50 %. Switching controllers work at 500kHz Hz. A nominal working status is achieved when the input voltage is set to 25V. It is not recommended to supply more current to the controller than 25mA. There is 11mA supply current for it. The nominal supply current for this the controllers dc is 17mA. For operation, the switching converter could be satisfied with 11mA current flow input.
