UC2844AD8 Overview
In the 8-SOIC (0.154, 3.90mm Width) package, the switching controller meets most application requirements. The dc motor controller is adquate to generate for 1 outputs. Tube solid enclosure protects the pmic. Transistor Driver dc switching's outputs (s) can be handled by it. dc controls with 10V~30V voltage are supplied and operated. Suitable for work in a -40°C~85°C TA dc switcher. Using this switching controller, it is possible to switch at Up to 500kHz. dc dc regulators can be carried out with Surface Mount. To provide efficient switching control, Frequency Control is included in the dcdc regulator. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. switching converters terminal (s) are designed to be at DUAL. An array of 8 terminations of dc switching. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. 15V nominal DC switcher's voltage input. UC2844 can be used to locate other relevant dc to dc converter ics. There are only 8 pins on switching converter. In particular, switching converter is a type of Switching Regulator or Controllers. A 15V voltage of DC regulator was detected in the test statistics. It's important to remember that the dc dc regulator's normaloutput current is 200mA, so you should note it down when starting a new project. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 50 %. Switching controller operates at 450kHz Hz. Input voltage can be set to 25V for nominal working status. Switching controller is necessary to provide a voltage of 11V. The controller should not be supplied with more current than 25mA. There is 17mA supply current for it. There is 17mA nominal current supply for this the controllers dc.
