IR3637SPBF Product Details

IR3637SPBF Overview


In the 8-SOIC (0.154, 3.90mm Width) package, the switching controller meets most application requirements. There is sufficient capacity to generate switching controller for outputs 1. There is a Tube solid enclosure around the pmic. With this function, you can deal with Transistor Driver dc switching's outputs (s). DC control operates at 4.5V~5.5V volts and has 4.5V~5.5V supply voltage. Suitable for working in an dc switcher that has a 0°C~125°C TJ. It can switch at 400kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. To provide efficient switching control, Enable, Soft Start is included in the dcdc regulator. In addition to "IR3637SPBF", there are other relevant dc to dc converter ics you can find. There are 8 pins on switching converter. DC regulator outputs 21.25V voltage based on test statistics. A starting point for a project is to note down the dc dc regulator's usual output current, which is 15A. Because of DC switcher's Surface Mount, it is suitable for most prototype designs and applications. DC regulator440kHz has the maximum frequency. A frequency of 400kHz is set for the switching controller. You should keep dc regulator at 0°C degrees or higher. There should be 125°C temperature above 125°C degrees Celsius when dc regulator runs. In dormant mode, 7mA is used. There would be 8-SOIC supplier dc dc controller package for this part. Voltage rating is 14V.
