UC3844ADTR Overview


As a result of 14-SOIC (0.154, 3.90mm Width) compact design, the switching controller is compatible with most applications. dc motor controller is suitable for 1 output generation. Tape & Reel (TR) is the solid enclosure in which PMIC is packaged. A total of Transistor Driver dc switching's outputs can be handled by it. The supply and operating voltage of the dc control are 10V~30V. Worked in an dc switcher with a 0°C~70°C TA rating. A switching controller such as this can switch at a value of Up to 500kHz . dc dc regulator is made easier with Surface Mount. Switching control is made easier with the dcdc regulator's Frequency Control. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. Thare switching converters has a terminal (s) at DUAL . Various 14 terminations. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. The nominal DC switcher's voltage input is 15V. Search for "UC3844" to find other relevant dc to dc converter ics. Switching converter has a total of 14 pins. In particular, switching converter is a type of Switching Regulator or Controllers. DC regulator outputs 15V voltage based on test statistics. 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. 450kHz is the frequency of the switching controller. For nominal working status, the input voltage can be set as 25V. Voltage 11V is required for supply. It is not recommended to supply more current to the controller than 25mA.
