UC3525AQ Overview


Capsuled in the 20-LCC (J-Lead) package, the switching controller can be used for a wide range of applications. For outputs of 2, this dc motor controller is suitable. PMIC is packaged in a solid enclosure of Tube. With Transistor Driver dc switching's output (s), it is able to handle it. dc controls with 8V~35V voltage are supplied and operated. Worked in a 0°C~70°C TA dc switcher before. This switching controller can switch at 100Hz~400kHz. dc dc regulator can be generalized using Surface Mount. To provide efficient switching control, Enable, Frequency Control, Soft Start is included in the dcdc regulator. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. There are a QUAD terminal on the switching converters. A variety of dc switching's functions can be performed on 20 terminations. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. DC switcher's input voltageis set to 20V. Searching "UC3525" will return other relevant dc to dc converter ics. In total, switching converter has 20 pins. Particularly, switching converter is a type of Switching Regulator or Controllers. DC regulator outputs 18V voltage based on test statistics. You should note that the dc dc regulator's usual output current is 100mA. It is set to 50 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. Switching controllers operate at 450kHz frequencies. In a dormant state, the dc switching uses 14mA. You can set the input voltage to 35V for nominal working status.
