UC3825ADWG4 Overview


Capsuled in the 16-SOIC (0.295, 7.50mm Width) package, the switching controller suits most application needs. For outputs of 2, this dc motor controller is suitable. An enclosure of Tube is used to package the PMIC. With Transistor Driver dc switching's output (s), it is able to handle it. This dc control has a supply voltage and operating voltage of 8.4V~22V. Suitable for working in an dc switcher that has a 0°C~70°C TA. The switching controller is capable of switching at the 400kHz~1MHz position. dc dc regulators can be carried out with Surface Mount. DCDC regulator is controlled efficiently by Current Limit, Frequency Control, Ramp, Soft Start. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. switching converters terminal (s) are designed to be at DUAL. 16 terminations with various dc switching's functions. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 12V is input. UC3825 can be used to locate other relevant dc to dc converter ics. In total, switching converter has 16 pins. In particular, switching converter belongs to the Switching Regulator or Controllers family. 8.8V should be the minimum input voltage for the dc dc voltage regulator. DC regulator outputs 2V voltage based on test statistics. In most cases, the output current of the dc dc regulator will be 200mA, so note that when you start the project. A duty cycle set at 50 % ensures voltage regulator dc to dc reliability during power-on and power-off. Switching controller operates at 1MHz Hz. Hence, CAN ALSO BE CONFIGURED IN CURRENT MODE is used to better suit the DC to DC voltage regulator's situation. The supply voltage should be 12V. Current supplied to the controller should not exceed 36mA.
