UC3525ADW Overview
It comes in the 16-SOIC (0.295, 7.50mm Width) package, which makes switching controller suitable for most applications. 2 outputs can be generated with the dc motor controller. PMIC packaging is solid with a Tube enclosure. Transistor Driver dc switching's outputs (s) are supported. A 8V~35V voltage is supplied to the dc control and used for operating it. Work well in dc switchers with a 0°C~70°C TA. The switching controller can be switched at 100Hz~400kHz. The Surface Mount value makes it suitable for general dc dc regulator. In order to control switching efficiently, the dcdc regulator features Enable, Frequency Control, Soft Start. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. The switching converters's terminals (s) are designed at DUAL. Various 16 terminations. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. DC switcher's input voltageis set to 20V. Other relevant dc to dc converter ics can be found by searching "UC3525". In total, switching converter has 16 pins. Switching converter is a type of Switching Regulator or Controllers in particular. 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. 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 500kHz Hz. As long as the dc switching is in a dormant state, it utilizes 14mA. Input voltage can be set to 35V for nominal working status.
