UC2825AQ Overview
With a 20-LCC (J-Lead) package, the switching controller is suitable for a wide range of applications. There is enough capacity in the dc motor controller to generate the output for the 2 input. PMIC packaging is solid with a Tube enclosure. There are Transistor Driver dc switching's output (s) that it can handle. This dc control operates at 8.4V~22V and has a 8.4V~22V supply voltage. Suitable for working in an dc switcher that has a -40°C~85°C TA. In this switching controller, the switch can be set to 400kHz~1MHz. The Surface Mount allows it to be used for dc dc regulator in general. Current Limit, Frequency Control, Ramp, Soft Start is used for efficient switching control in the dcdc regulator. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. Thare switching converters has a terminal (s) at QUAD . A variety of dc switching's functions can be performed on 20 terminations. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. 12V nominal DC switcher's voltage input. In addition to "UC2825", there are other relevant dc to dc converter ics you can find. Pins number 20 of switching converter in total. Specifically, switching converter falls under the Switching Regulator or Controllers category. Input voltage of dc dc voltage regulator should be 8.8V. The test statistics indicate that DC regulator outputs a voltage of 2V. 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. As a result of this, the maximum duty cycle of the voltage regulator dc to dc must remain 50 % during power-up and power-down. Switching controller operates at a frequency of 1MHz. The value of DC to DC voltage regulator is set at CAN ALSO BE CONFIGURED IN CURRENT MODE in order to fulfill the requirements more effectively.
