UC3526AQ Overview
In the 20-LCC (J-Lead) package, the switching controller meets most application requirements. For outputs of 2, this dc motor controller is suitable. Tube solid enclosure protects the pmic. With Transistor Driver dc switching's output (s), it is able to handle it. DC control operates at 7V~35V volts and has 7V~35V supply voltage. Qualified to work in an dc switcher with 0°C~70°C TA. Using this switching controller, it is possible to switch at 1Hz~600kHz. dc dc regulator can be generalized using Surface Mount. Featured in the dcdc regulator is Enable, Frequency Control, Reset, Soft Start which allows efficient switching control. The switch converters are connected to a SWITCHING CONTROLLER analog IC. There are a terminal (s) on the switching converters that are designed at QUAD. Various 20 terminations. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. DC switcher's input voltageis set to 15V. You can find other relevant dc to dc converter ics by searching "UC3526". There are 20 pins on switching converter. In particular, switching converter belongs to the Switching Regulator or Controllers family. Test statistics indicate DC regulator outputs 13V voltage. You should note down the dc dc regulator's usual output current of 100mA when you start a project. The maximum duty cycle of this voltage regulator dc to dc is set to 50 % to ensure reliability during power-up and power-down. Switching controllers operate at 450kHz frequencies. Input voltage can be set to 35V for nominal working status.
