MAX8743ETX+ Overview
In the 36-WFQFN Exposed Pad package, the switching controller meets most application requirements. For outputs of 2, this dc motor controller is suitable. The pmic is packaged in Tube solid enclosure. With this function, you can deal with Transistor Driver dc switching's outputs (s). DC control operates at 2V~28V volts and has 2V~28V supply voltage. Worked in an dc switcher with a -40°C~85°C TA rating. Using this switching controller, it is possible to switch at 200kHz 300kHz 420kHz 540kHz. To ensure efficient switching, this dcdc regulator features a Current Limit, Enable, On Time Control, Power Good, Pulse Skipping. Connected to a DUAL SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. Switching converters are designed with the terminal (s) at position QUAD . 36 terminations with various dc switching's functions. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. 5V nominal DC switcher's voltage input. Specifically, switching converter falls under the Switching Regulator or Controllers category. This dc dc voltage regulator should be powered by a voltage of 4.5V. It should be noted that the dc to dc regulator only accepts 5.5V voltage as input voltage. 3A is the greatest value switching converter outputs as current.
