UC3825AQ Overview
Capsuled in the 20-LCC (J-Lead) package, the switching controller suits most application needs. For outputs of 2, this dc motor controller is suitable. Tube is the solid enclosure in which PMIC is packaged. The system can process Transistor Driver dc switching's outputs (s). Voltages 8.4V~22V are the dc control's supply voltage and operating voltage, respectively. Qualified to work in an dc switcher with 0°C~70°C TA. In this switching controller, the switch can be set to 400kHz~1MHz. As it has a Surface Mount value, it can be used for general dc dc regulator. Current Limit, Frequency Control, Ramp, Soft Start is used for efficient switching control in the dcdc regulator. The switch converters are connected to a SWITCHING CONTROLLER analog IC. There are a QUAD terminal on the switching converters. 20 terminations with various dc switching's functions. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 12V. DC to DC voltage regulator has the value of HALF DUTY to better satisfy the requirement.
