UC3844ANG4 Overview


This switching controller fits most application requirements since it is packaged in a 8-DIP (0.300, 7.62mm) package. dc motor controller is suitable for 1 output generation. There is a Tube solid enclosure around the pmic. A total of Transistor Driver dc switching's outputs can be handled by it. DC control operates at 10V~30V volts and has 10V~30V supply voltage. Worked in a 0°C~70°C TA dc switcher before. There is a switch at Up to 500kHz that can be used with this controller. dc dc regulator can be generalized using Through Hole. Featured in the dcdc regulator is Frequency Control which allows efficient switching control. SWITCHING CONTROLLER analog IC connects the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. A variety of dc switching's functions can be performed on 8 terminations. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 15V. Search for "UC3844" to find other relevant dc to dc converter ics. The switching converter has a total of 8 pins. Specially, switching converter corresponds to type Switching Regulator or Controllers. Based on the test statistics, DC regulator outputs voltage 15V. In most cases, the dc dc regulator's output current is 200mA. This information should be noted when you begin working with the component. The maximum duty cycle of this voltage regulator dc to dc is set to 50 % to ensure reliability during power-up and power-down. 450kHz is the frequency of the switching controller. A nominal working status is achieved when the input voltage is set to 25V. A supply voltage of 11V is required. It is important that the controller is supplied with 25mA more than 25mA volts of current.
