IR3640MPBF Overview


This switching controller fits most application requirements since it is packaged in a 20-VFQFN Exposed Pad package. dc motor controller is suitable for 1 output generation. Packaging for the pmic consists of Tube solid enclosures. With Transistor Driver dc switching's output (s), it is able to handle it. dc controls with 4.5V~5.5V voltage are supplied and operated. Qualified to work in a -40°C~125°C TJ dc switcher. With this switching controller, you can switch at 225kHz~1.65MHz. Surface Mount makes it suitable for general dc dc regulator. Current Limit, Enable, Frequency Control, Power Good, Sequencing, Soft Start provides dcdc regulator efficient switching control. Other relevant dc to dc converter ics can be found by searching "IR3640MPBF". 20 pins are present on switching converter. Statistically, DC regulator outputs 21.6V volts. It's important to remember that the dc dc regulator's normaloutput current is 1kA, so you should note it down when starting a new project. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 92 %. Having a Surface Mount makes DC switcher suitable for most application and prototype designs. There is a maximum frequency of 1.65MHz for this dc regulators. You should keep dc regulator at -40°C degrees or higher. A temperature of 125°C more than 125°C degrees Celsius should be maintained in the undc regulator. There would be 20-MLPQ (3x4) supplier dc dc controller package for this part. According to its maximum supply voltage rating, the voltage controller is rated 5.5V.
