LT3840EUFE#PBF Overview
In the 38-WFQFN Exposed Pad package, the switching controller meets most application requirements. It is sufficient to generate 1 outputs with this dc motor controller. PMIC is packaged in a solid enclosure of Tube. With Transistor Driver dc switching's output (s), it is able to handle it. dc control's supply and operating voltages are 2.5V~60V. Suitable for a -40°C~125°C TJ dc switcher. Using this switching controller, it is possible to switch at 50kHz~1MHz. A generalization of dc dc regulator can be made using Surface Mount. To provide efficient switching control, Enable, Frequency Control, Power Good, Soft Start, Tracking is included in the dcdc regulator. The switch converters are connected to a SWITCHING CONTROLLER analog IC. The switching converters's terminal (s) are designed at QUAD . An array of 38 terminations of dc switching. You can find other relevant dc to dc converter ics by searching "LT3840". There are 38 pins on switching converter. DC regulator outputs 1.5V voltage based on test statistics. In most cases, the dc dc regulator's output current is 30A. This information should be noted when you begin working with the component. The duty cycle of the voltage regulator dc to dc can be set to 99 % on power-up or power-down to ensure reliability. The dc switcher's maximum input voltage is 60V; users must limit it accordingly. Switching controller is necessary to have a supply voltage of 2.5V. At its maximum, the switching converter can output 60V volts. A voltage controller's lowest output voltage cannot be less than 1.5V.
