LTC3780EUH Overview


With its 32-WFQFN Exposed Pad package, the switching controller fits the needs of most applications. There is enough capacity in the dc motor controller to generate the output for the 1 input. The pmic is packaged in Tube solid enclosure. It is capable of handling Transistor Driver dc switching's outputs (s). dc control's supply and operating voltages are 4V~30V. Workable in an dc switcher where -40°C~85°C TJ is the -40°C~85°C TJrm. In this switching controller, the switch can be set to 200kHz~400kHz. It is suitable for general dc dc regulator when it is set to Surface Mount. Current Limit, Enable, Power Good, Soft Start is used for efficient switching control in the dcdc regulator. An analog IC SWITCHING CONTROLLER is connected to the switch converters. Switching converters are designed with the terminal (s) at position QUAD . The 32 terminations can be used for a wide range of dc switching. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. You can find other relevant dc to dc converter ics by searching "LTC3780". There is a particular type of Switching Regulator or Controllers in switching converter. dc dc voltage regulators should have a minimum input voltage of 4V. The dc to dc regulator can only accept 36V input voltage. In order to satisfy the need, DC to DC voltage regulator has a value of ALSO OUTPUT VOLTAGE ADJUSTABLE 0.8 TO 30V. Whenever the current value is 3A, switching converter outputs the highest possible value.
