LM2647LQ Overview


With a 28-WFQFN Exposed Pad package, the switching controller is suitable for a wide range of applications. dc motor controller is suitable for 2 output generation. Tape & Reel (TR) is the solid enclosure in which PMIC is packaged. A total of Transistor Driver dc switching's outputs can be handled by it. dc control's supply and operating voltages are 5.5V~28V. Qualified to work in an dc switcher with -5°C~125°C TJ. The switching controller can be switched at 200kHz~500kHz. A generalization of dc dc regulator can be made using Surface Mount. To ensure efficient switching, this dcdc regulator features a Current Limit, Enable, Frequency Control, Power Good, Soft Start. A DUAL SWITCHING CONTROLLER analog IC is connected to the switch converters. switching converters terminal (s) are designed to be at QUAD. Different dc switching's functions can be applied to 28 terminations. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 5V is input. Searching "LM2647" will return other relevant dc to dc converter ics. The switching converter has a total of 28 pins. There is a particular type of Switching Regulator or Controllers in switching converter. The test statistics indicate that DC regulator outputs a voltage of 5V. If you are starting a new project, you should note the dc dc regulator's typical output current is 20A. Because of DC switcher's Surface Mount, it is suitable for most prototype designs and applications. The switching controller works at a frequency of 345kHz. To run the voltage regulator dc to dc safely and reliably, users should apply 28V to the voltage regulator dc to dc. In dormant mode, 2.5mA is used.
