UC2844AQD Overview


Capsuled in the 14-SOIC (0.154, 3.90mm Width) package, the switching controller can be used for a wide range of applications. There is enough capacity in the dc motor controller to generate the output for the 1 input. PMIC is packaged in a solid enclosure of Tube. With this function, you can deal with Transistor Driver dc switching's outputs (s). dc control's supply and operating voltages are 10V~30V. A -40°C~125°C TA dc switcher is not a problem. With this switching controller, you can switch at Up to 500kHz. dc dc regulator can be generalized using Surface Mount. Featured in the dcdc regulator is Frequency Control which allows efficient switching control. An analog IC SWITCHING CONTROLLER is connected to the switch converters. There are a terminal (s) on the switching converters that are designed at DUAL. 14 terminations with various dc switching's functions. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's voltage input of 15V. You can find other relevant dc to dc converter ics by searching "UC2844". 14 pins are on switching converter. Particularly, switching converter is a type of Switching Regulator or Controllers. Statistically, DC regulator outputs 15V volts. The dc to dc regulator can only accept 25V input voltage. If you are starting a new project, you should note the dc dc regulator's typical output current is 200mA. A duty cycle set at 50 % ensures voltage regulator dc to dc reliability during power-on and power-off. Switching controllers operate at 450kHz frequencies. If the user wishes to run the voltage regulator dc to dc in a circuit safely and reliably, they should apply 30V. The dc switching utilizes 11mA when it is in a dormant state.
