UC3525BN Overview


This switching controller fits most application requirements since it is packaged in a 16-DIP (0.300, 7.62mm) package. dc motor controller is suitable for 2 output generation. Packaging for the pmic consists of Tube solid enclosures. Transistor Driver dc switching's outputs (s) are supported. dc control's supply and operating voltages are 8V~35V. Qualified to work in an dc switcher with 0°C~70°C TA. The switching controller can be switched at 100Hz~400kHz. The Through Hole makes it ideal for general dc dc regulator. Dead Time Control, Frequency Control, Ramp, Soft Start is used for efficient switching control in the dcdc regulator. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. Switching converters are designed with the terminal (s) at position DUAL . Different dc switching's functions can be applied to 16 terminations. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 20V. A search for "UC3525" will reveal other relevant dc to dc converter ics. In total, switching converter has 16 pins. Switching converter is a special type of Switching Regulator or Controllers. A 18V voltage of DC regulator was detected in the test statistics. In most cases, the output current of the dc dc regulator will be 100mA, so note that when you start the project. As a result of this, the maximum duty cycle of the voltage regulator dc to dc must remain 50 % during power-up and power-down. Switching controllers operate at 450kHz frequencies. In dormant mode, 14mA is used. It is possible to set the input voltage to 35V for nominal working status.
