UC3844D Overview

With a 14-SOIC (0.154, 3.90mm Width) package, the switching controller is suitable for a wide range of applications. There is sufficient capacity to generate switching controller for outputs 1. The pmic is packaged in Tube solid enclosure. The program can handle Transistor Driver dc switching's outputs (s). This dc control operates at 12V~28V and has a 12V~28V supply voltage. Work well in dc switchers with a 0°C~70°C TA. There is a switch at Up to 500kHz that can be used with this controller. The Surface Mount value makes it suitable for general dc dc regulator. Frequency Control is used for efficient switching control in the dcdc regulator. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. switching converters terminal (s) are designed to be at DUAL. A variety of 14 terminations are available in dc switching. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 15V. You can find other relevant dc to dc converter ics by searching "UC3844". The switching converter has a total of 14 pins. Particularly, switching converter is a type of Switching Regulator or Controllers. Statistically, DC regulator outputs 13.5V volts. 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. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 50 %. The switching controller works at a frequency of 450kHz. During dormancy, the dc switching uses 11mA. It is possible to set the input voltage to 25V for nominal working status. There will be 1A output current greater than 1A from the dc switcher. It is not recommended to supply more current to the controller than 25mA.
