UC3844DTRG4 Overview
With a 14-SOIC (0.154, 3.90mm Width) package, the switching controller is suitable for a wide range of applications. For 1 outputs, the dc motor controller is appropriate. A solid enclosure of Tape & Reel (TR) surrounds pmic. With this function, you can deal with Transistor Driver dc switching's outputs (s). dc controls with 12V~28V voltage are supplied and operated. Suitable for a 0°C~70°C TA dc switcher. A switching controller such as this can switch at a value of Up to 500kHz . Surface Mount makes it suitable for general dc dc regulator. Featured in the dcdc regulator is Frequency Control which allows efficient switching control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. Thare switching converters has a terminal (s) at DUAL . 14 terminations with various dc switching's functions. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. DC switcher's voltage input of 15V. A search for "UC3844" will reveal other relevant dc to dc converter ics. In total, switching converter has 14 pins. In particular, switching converter is a type of Switching Regulator or Controllers. Statistically, the DC regulator outputs 13.5V voltage. normally, the dc dc regulator's output current is 200mA, which you should keep in mind when starting a project. As a result of this, the maximum duty cycle of the voltage regulator dc to dc must remain 50 % during power-up and power-down. Switching controllers operate at 450kHz frequencies. Input voltage can be set to 25V for nominal working status. A controller's current should not exceed 25mA.
