UC3825DWTR Overview
Capsuled in the 16-SOIC (0.295, 7.50mm Width) package, the switching controller can be used for a wide range of applications. 2 outputs are supported by the dc motor controller. There is a Tape & Reel (TR) solid enclosure around the pmic. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sVoltages 8.4V~30V are the dc control's supply voltage and operating voltage, respectively. Work well in dc switchers with a 0°C~70°C TA. Switching can be done at 340kHz~460kHz with this switching controller. As it has a Surface Mount value, it can be used for general dc dc regulator. Current Limit, Enable, Frequency Control, Ramp, Soft Start provides dcdc regulator efficient switching control. The switch converters are connected to a SWITCHING CONTROLLER analog IC. A switching converters's terminal (s) sits at the DUAL position. A variety of terminations with 16 of dc switching. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 15V. Other relevant dc to dc converter ics can be found by searching "UC3825". The switching converter has a total of 16 pins. There is a particular type of Switching Regulator or Controllers in switching converter. It is recommended to use 8.8V as the minimum input voltage of dc dc voltage regulator. As determined by the test statistics, the output voltage of DC regulator is 13V. Considering the dc to dc regulator can only accept 30V input voltage, it is important to take note of this. If you are starting a new project, you should note the dc dc regulator's typical output current is 200mA. The duty cycle of the voltage regulator dc to dc can be set to 85 % on power-up or power-down to ensure reliability. Switching controller operates at 1MHz Hz. As a result, DC to DC voltage regulator has a value of CAN ALSO BE CONFIGURED IN CURRENT MODE so that the need can be met more directly. Switching controller is necessary to provide a voltage of 15V. It is not recommended to supply more current to the controller than 33mA.
