UC2844AD8G4 Overview


With its 8-SOIC (0.154, 3.90mm Width) package, the switching controller fits the needs of most applications. 1 outputs can be generated with the dc motor controller. An enclosure of Tube is used to package the PMIC. With Transistor Driver dc switching's output (s), it is able to handle it. Voltages 10V~30V are the dc control's supply voltage and operating voltage, respectively. Worked in an dc switcher with a -40°C~85°C TA rating. This switching controller can switch at Up to 500kHz. The Surface Mount makes it ideal for general dc dc regulator. Switching control is made easier with the dcdc regulator's Frequency Control. SWITCHING CONTROLLER analog IC connects the switch converters. Thare switching converters has a terminal (s) at DUAL . A variety of 8 terminations are available in dc switching. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. UC2844 can be used to locate other relevant dc to dc converter ics. There are 8 pins on switching converter. Switching converter is a type of Switching Regulator or Controllers in particular. A 5.1V voltage of DC regulator was detected in the test statistics. You should note that the dc dc regulator's usual output current is 200mA. The duty cycle of the voltage regulator dc to dc can be set to 50 % on power-up or power-down to ensure reliability. Switching controller operates at 500kHz Hz. It is possible to set the input voltage as 25V for nominal working statuses. The supply voltage must be 11V. 25mA more than 25mA current should be supplied to the controller. For operation, the switching converter could be satisfied with 11mA current flow input.
