UC3525AQG3 Overview
Capsuled in the 20-LCC (J-Lead) package, the switching controller can be used for a wide range of applications. The dc motor controller is adquate to generate for 2 outputs. Packaged in solid enclosures, this pmic has a Tube rating. With Transistor Driver dc switching's output (s), it is able to handle it. The supply and operating voltage of the dc control are 8V~35V. Qualified to work in a 0°C~70°C TA dc switcher. With this switching controller, you can switch at 100Hz~400kHz. dc dc regulator is made easier with Surface Mount. Enable, Frequency Control, Soft Start is used for efficient switching control in the dcdc regulator. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. There are a QUAD terminal on the switching converters. An array of 20 terminations of dc switching. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. There is a DC switcher's nominal voltage of 20V. UC3525 can be used to locate other relevant dc to dc converter ics. There are only 20 pins on switching converter. Switching converter is a type of Switching Regulator or Controllers in particular. Statistically, the DC regulator outputs 18V voltage. In most cases, the dc dc regulator's output current is 100mA. 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 controllers operate at 450kHz frequencies. It is possible to set the input voltage as 35V for nominal working statuses.
