LTC3780IUH#PBF Overview


The switching controller fits in the 32-WFQFN Exposed Pad package and is ideal for most applications. It is sufficient to generate 1 outputs with this dc motor controller. Tube solid enclosure protects the pmic. A total of Transistor Driver dc switching's outputs can be handled by it. The supply and operating voltage of the dc control are 4V~30V. Workable in an dc switcher where -40°C~125°C TJ is the -40°C~125°C TJrm. A switching controller such as this can switch at a value of 200kHz~400kHz . The Surface Mount allows it to be used for dc dc regulator in general. In order to control switching efficiently, the dcdc regulator features Current Limit, Enable, Power Good, Soft Start. SWITCHING CONTROLLER analog IC connects the switch converters. There are a terminal (s) on the switching converters that are designed at QUAD. An array of 32 terminations of dc switching. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. 15V nominal DC switcher's voltage input. LTC3780 can be searched for other relevant dc to dc converter ics. Specially, switching converter corresponds to type Switching Regulator or Controllers. dc dc voltage regulators should have a minimum input voltage of 4V. Considering the dc to dc regulator can only accept 36V input voltage, it is important to take note of this. In order to satisfy the need, DC to DC voltage regulator has a value of ALSO OUTPUT VOLTAGE ADJUSTABLE 0.8 TO 30V. 3A is the largest value switching converter outputs.
