UC3525BDW Overview
It comes in a 16-SOIC (0.295, 7.50mm Width) package, so switching controller can be used for most applications. 2 outputs are supported by the dc motor controller. PMIC is packaged in a solid enclosure of Tube. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching's8V~35V is the supply voltage and the operating voltage of the dc control. Worked in a 0°C~70°C TA dc switcher before. The switching controller is capable of switching at the 100Hz~400kHz position. dc dc regulator is made easier with Surface Mount. Dead Time Control, Frequency Control, Ramp, Soft Start is used for efficient switching control in the dcdc regulator. A SWITCHING CONTROLLER analog IC is connected to the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. The 16 terminations can be used for a wide range of dc switching. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 20V. In addition to "UC3525", there are other relevant dc to dc converter ics you can find. Switching converter has a total of 16 pins. Specially, switching converter corresponds to type Switching Regulator or Controllers. The test statistics indicate that DC regulator outputs a voltage of 18V. You should note that the dc dc regulator's usual output current is 100mA. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 50 %. Switching controller operates at a frequency of 450kHz. In dormant mode, 14mA is used. It is possible to set the input voltage to 35V for nominal working status.
