UC2844D8G4 Overview


It comes in the 8-SOIC (0.154, 3.90mm Width) package, which makes switching controller suitable for most applications. There is sufficient capacity to generate switching controller for outputs 1. PMIC packaging is solid with a Tube enclosure. Transistor Driver dc switching's outputs (s) can be handled by it. Voltages 12V~28V 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. dc dc regulators can be carried out with 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. The switching converters's terminal (s) are designed at DUAL . An array of 8 terminations of dc switching. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. The DC switcher's nominal voltage is 15V. Search for "UC2844" to find other relevant dc to dc converter ics. Total pins of switching converter are 8. Particularly, switching converter is a type of Switching Regulator or Controllers. According to the test statistics, DC regulator outputs 13.5V voltage. You should note that the dc dc regulator's usual output current is 200mA. A duty cycle set at 50 % ensures voltage regulator dc to dc reliability during power-on and power-off. The switching controller works at a frequency of 450kHz. For nominal working status, the input voltage can be set as 25V. The controller should not be supplied with more current than 25mA.
