UC3525AN Overview
In the 16-DIP (0.300, 7.62mm) package, the switching controller meets most application requirements. There is enough capacity in the dc motor controller to generate the output for the 2 input. PMIC is packaged in a solid enclosure of Tube. The system can process Transistor Driver dc switching's outputs (s). dc control's supply and operating voltages are 8V~35V. Suitable for working in an dc switcher that has a 0°C~70°C TA. A switching controller such as this can switch at a value of 100Hz~400kHz . dc dc regulator can be generalized using Through Hole. DCDC regulator is controlled efficiently by Enable, Frequency Control, Soft Start. A SWITCHING CONTROLLER analog IC is connected to the switch converters. The switching converters's terminals (s) are designed at DUAL. The 16 terminations can be used for a wide range of dc switching. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 20V. You can find other relevant dc to dc converter ics by searching "UC3525". There are only 16 pins on switching converter. Specially, switching converter corresponds to type Switching Regulator or Controllers. DC regulator outputs 18V voltage according to the test statistics. In most cases, the dc dc regulator's output current is 200mA. This information should be noted when you begin working with the component. To ensure the reliability under power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set as 50 %. Switching controller operates at 450kHz Hz. In dormant mode, 14mA is used. Input voltage can be set to 35V for nominal working status.
