LTC3731CG#PBF Overview


With its 36-SSOP (0.209, 5.30mm Width) package, the switching controller fits the needs of most applications. dc motor controller is suitable for 3 output generation. A solid enclosure of Tube surrounds pmic. There are Transistor Driver dc switching's output (s) that it can handle. 3.8V~7V is the operating voltage and supply voltage of the dc control. Worked in an dc switcher with a 0°C~70°C TA rating. A switching controller such as this can switch at a value of 225kHz~680kHz . The Surface Mount value makes it suitable for general dc dc regulator. To ensure efficient switching, this dcdc regulator features a Enable, Phase Control, Power Good, Soft Start. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. Thare switching converters has a terminal (s) at DUAL . 36 terminations with a variety of function. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. DC switcher's input voltageis set to 5V. Other relevant dc to dc converter ics can be found by searching "LTC3731". In total, switching converter has 36 pins. Specifically, switching converter falls under the Switching Regulator or Controllers category. It is recommended that the dc dc voltage regulator's minimum input voltage be 4.5V. DC regulator outputs 32V voltage based on test statistics. normally, the dc dc regulator's output current is 5A, which you should keep in mind when starting a project. 600kHz is the frequency of the switching controller. PolyPhase? series dc to dc voltage regulator belong to this series. Channels are 1 for high-quality communication.
