UC3525AQTR Overview
With its 20-LCC (J-Lead) package, the switching controller fits the needs of most applications. 2 outputs can be generated with the dc motor controller. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. There are Transistor Driver dc switching's output (s) that it can handle. Voltages 8V~35V 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 100Hz~400kHz. dc dc regulator can be generalized using Surface Mount. Enable, Frequency Control, Soft Start is used for efficient switching control in the dcdc regulator. An analog IC SWITCHING CONTROLLER is connected to the switch converters. The switching converters's terminal (s) are designed at QUAD . A variety of 20 terminations are available in dc switching. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's voltage input is 20V. You can find other relevant dc to dc converter ics by searching "UC3525". There are a total of 20 pins on switching converter. In particular, switching converter belongs to the Switching Regulator or Controllers family. The test statistics indicate that DC regulator outputs a voltage of 18V. The dc dc regulator's usual output current is 100mA, which should be noted down when you start a project. It is set to 49 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. In most applications and prototype designs, DC switcher is qualified as a Surface Mount. Switching controllers operate at 450kHz frequencies. If the user wishes to run the voltage regulator dc to dc in a circuit safely and reliably, they should apply 35V. 35V is the nominal working voltage.
