UC2844NG4 Overview

It comes in the 8-DIP (0.300, 7.62mm) package, which makes switching controller suitable for most applications. For 1 outputs, the dc motor controller is appropriate. Tube solid enclosure protects the pmic. There are Transistor Driver dc switching's output (s) that it can handle. This dc control operates at 12V~28V and has a 12V~28V supply voltage. Suitable for a -40°C~85°C TA dc switcher. A switching controller such as this can switch at a value of Up to 500kHz . Through Hole makes it suitable for general dc dc regulator. Featured in the dcdc regulator is Frequency Control which allows efficient switching control. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. DUAL are the position of the terminal of the switching converters. 8 terminations with a variety of function. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. 15V nominal DC switcher's voltage input. You can find other relevant dc to dc converter ics by searching "UC2844". Total pins of switching converter are 8. In particular, switching converter is a type of Switching Regulator or Controllers. Statistically, the DC regulator outputs 13.5V voltage. If you start a project, note down the dc dc regulator's usual output current of 200mA. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 50 %. The switching controller works at a frequency of 500kHz. For nominal working status, the input voltage can be set as 25V. Because the dc switcher's maximum input voltage is 25V users must limit the voltage accordingly. DC switchers cannot produce output currents greater than 1A. You should not supply more current than 25mA to the controller. It could be possible to satisfy the switching converter for operation with a current flow input of 11mA.
