LTC3731IUH#PBF Overview


The switching controller fits in the 32-WFQFN Exposed Pad package and is ideal for most applications. There is sufficient capacity to generate switching controller for outputs 3. The pmic is packaged in Tube solid enclosure. It is capable of handling Transistor Driver dc switching's outputs (s). DC control operates at 3.8V~7V volts and has 3.8V~7V supply voltage. Qualified to work in a -40°C~85°C TA dc switcher. Using this switching controller, it is possible to switch at 225kHz~680kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. To provide efficient switching control, Enable, Phase Control, Power Good, Soft Start is included in the dcdc regulator. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. QUAD are the position of the terminal of the switching converters. Various 32 terminations. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. 5V nominal DC switcher's voltage input. You can find other relevant dc to dc converter ics by searching "LTC3731". 32 pins are on switching converter. Particularly, switching converter is a type of Switching Regulator or Controllers. Based on the test statistics, DC regulator outputs voltage 6V. The dc dc regulator's usual output current is 5A, which should be noted down when you start a project. Switching controller operates at 400kHz Hz. Thare are switch converters of the PolyPhase? series. It is possible to set the input voltage as 28V for nominal working statuses. Channels are 1 for high-quality communication.
